Abstract:
Cylindrical shells are principal structural elements that are used for many purposes, such as offshore, sub-marine, and airborne structures. The nonlinear mechanics model of internal blast loading was established to predict the dynamic blast pressure of cylindrical shells. However, due to the complexity of the nonlinear mechanical model, the solution process is time-consuming. In this study, the nonlinear mechanics model of internal blast loading is linearized, and the dynamic blast pressure of cylindrical shells is solved. First, a mechanical model of cylindrical shells subjected to internal blast loading is proposed. To simplify the calculation, the internal blast loading is reduced to linearly uniform variations. Second, according to the stress function method, the dynamic blast pressure equation of cylindrical shells subjected to blast loading is derived. Third, the calculated results are compared with those of the finite element method (FEM) under different durations of dynamic pressure pulse. Finally, to reduce the errors, the dynamic blast pressure equation is further optimized. The results demonstrate that the optimized equation is in good agreement with the FEM, and is feasible to linearize the internal blast loading of cylindrical shells.

Abstract:
A sacrificial cladding consist of hollow metal tubes and steel sheet, is proposed in this study to protect a square concrete panel subjected to blast loading. Herein, comparative analysis of aluminum alloy 6061-T6 (Al 6061-T6) and mild steel tubes in sacrificial cladding is done using 3-D non-linear Finite Element (FE) software ABAQUS/Explicit®. Blast load is applied through ConWep program developed by US Army. Simplified Concrete Damage Plasticity (SCDP) model is used to define the material behavior of concrete slabs of thickness 250 mm. Johnson-Cook (J-C) plasticity model is used to model the stress-strain response of Al 6061-T6 and mild steel tubes, reinforcement bars and steel sheet. Diameter (D) and thickness (t) of circular metal hollow tubes are taken from IS1161:1998. Comparative analysis of Al 6061-T6 and mild steel tubes is carried out for blast loading using TNT with scaled distance of 0.425 m/kg1/3. It was observed that mild steel tubes perform better than Al 6061-T6 tubes and save concrete panel from degradation under blast loading.

Abstract:
Dynamic fracture of explosion containment vessels subjected to internal blast loads is the foundation for conducting safety assessment and failure analysis of explosion containment vessels. The experiments were carried out to investigate dynamic fracture characteristics of cylindrical steel shells subjected to internal blast loadings at the centers. The elastic-plastic response of cylindrical steel shells was conducted using nonlinear dynamic finite element analysis code LS-DYNA. The fracture mode and fracture mechanism of a cylindrical shell were specially studied through analysis of deformation， macrographs of fracture surface and elastic-plastic response. The results show that dynamical ductility deformations appear and the shear bands form when the cylindrical steel shell expands under internal blast loading. The cylindrical steel shell fractures preferentially along the shear bands due to its softening effect. The fracture mechanism is that the shear bands tear under tensile circumferential stress. The shear bands and the tensile circumferential stress dominate the final fracture mode. The fracture mode is of the ductile fracture.

Abstract:
Cylindrical explosive loading has an important application in explosive working, researching on weapon damage, and explosive-driving load. This study uses experimental and numerical methods to study the response of long and thin tubes when subjected to cylindrical explosive loading. The flake-like charge and multipoint initiation technique were adopted to load cylindrical explosive waves. Experimental results showed that the method could produce uniform deformation in certain parts of the long tube, but partial spall injuries occurred after the explosion. The macroscopic and microscopic deformation of tubes were analyzed. Numerical simulations were conducted to investigate the detailed response of the tube subjected to a cylindrical explosive wave. The results indicate that the collision of explosive waves brought inconsistencies in pressure and velocity. The pressure and velocity in the collision region were significantly higher than those of other parts, which caused the collision region to be easily damaged.

The purpose of the present paper is to investigate the influence of charge shape on the air blast loading near the explosive. By using MSC. DYTRAN, the air blast loading of spherical charge, cubical charge and cylindrical charge with the same weight were simulated. After the characters of shock wave, peak pressure and impulse of such three charges were compared, it can be seen that there are different decay law for peak pressure of cylindrical charge, cubical charge, spherical and experiment formula. There are also different magnitude relation for the impulse at different scaling distance.

Broken rules of cylindrical steel shell subjected to internal blast loads is the foundation for conducting safety assessment and failure analysis of explosion containment vessels. The experiments were carried out broken rules of the cylindrical steel shells subjected to internal blast loadings at the centers. The elastic-plastic response of cylindrical steel shells was conducted using nonlinear dynamic finite element analysis code LS-DYNA. The results show that the deformation was’t a discrepancy in the explosion center of the cylindrical steel shell in same space, and the deformation descended slower along with thickness augmentation in the end of explosion center. The radial stress、hoop stress and axial stress was a discrepancy in the thickness way of cylindrical steel shell of explosion center The most leading cause of destructivity of cylindrical steel shell was that inner wall bearing normal stress and exterior wall bearing tensile stress; the hoop stress was broken more than axial stress cylindrical steel shell. The whole process was presenting hoop fractured and axial growth.

Abstract:
According to the assessments of the United Nations, there are more than 100 million mines lying buried in various conflict zones of many countries in the world. As per their assessment, many thousand casualties happen every year. Most of the demining operations are generally carried out after the conflicts end. This task is one of the most challenging and always a risky operation. There are various demining equipment available world-wide to perform this job in addition to the manual demining of minefield by trained soldiers. Explosive loading on machine components of service vehicles during military operations is a complex process. The complexity stems from unpredictable detonation, complicated component geometry and geographical terrain, debris effects etc. Consequently, the damage on structural components becomes highly unpredictable. There are too many other environmental parameters contributing to the final damage. In this context, both high explosive loading and material response behave like independent random variables. Blast loading on tubes and plates is vital in the design of combat and demining equipment of real life situations. Therefore, study of plain circular tubes (PCT), perforated circular tubes (PRCT) and plates subjected to blast loading due to explosion of high explosives such as TNT, RDX and TETRYL has been considered in the present thesis. Due to various design constraints, it is extremely difficult to design these components for desired service life for high quantum of blast load. This thesis explains the uses of perforations for handling this inevitable and extreme condition of loading on the target components. It is pertinent to note that the various blast parameters such as time of sight, overpressure, impulse etc. available in the literature are not reliable for close range of explosion of high explosive for scaled distance in order of 0.40 m/kg1/3. Therefore, it is essential to establish and quantify some of these parameters for close range blast, which will be useful for real life design problems. Accordingly, the present thesis covers experimental and numerical study of plain circular tube (PCT) and perforated circular tube (PRCT) under blast loading of high explosive. iv CONWEP code has been used for numerical simulation of PCT and PRCT subjected to blast loading. Some important blast parameters have been established in this research. It has been shown that there is approximately 58 % reduction in blast impact on the tube due to use of perforation. Square and hexagonal pattern of perforation has been studied. Theory of strong explosion has been discussed in the present thesis. Non-dimensional time and length scale has been proposed in place of scaled distance. Also, simplified empirical formula has been proposed for estimation of time of sight for close range blast covering scaled distance 0.40 m/kg1/3 - 0.45 m/kg1/3.

Abstract:
Blasts and impacts are two of the severest loads a structure can experience. Blast experimenters, however, have observed that the load imparted to a circular member was lower than the predicted design load. Additionally, numerous investigations have established the superiority of concrete filled FRP tubes (CFFTs) over conventional reinforced concrete members. These observations indicated CFFTs’ potential to resist dynamic blast and impact loads. The experimental and numerical investigations presented in this thesis aimed to demonstrate the suitability of CFFTs to resist blast and impact loads, to determine the parameters that influence their behaviour under such loads, and to develop a design procedure for resisting these loads. The initial numerical investigation determined the reflected blast loading parameters experienced by a circular cross section. The experimental phase consisted of testing twelve full scale specimens, two monotonically, four under impact loading, and six under close-in blast loading. The monotonically tested specimens acted as controls for the entire program. The results of the impact testing investigation were used to develop and validate a non-linear single degree of freedom (SDOF) model. This impact phase also led to the development of relatively simple procedures for designing CFFTs under impact loading using either SDOF modeling or the conservation of energy. Analysis of the blast testing results led to the development of numerical procedures for obtaining an equivalent close-in blast loading for SDOF analysis of CFFTs and Pressure-Impulse diagrams. The use of SDOF modeling and conservation of energy in blast design were also discussed. Finally, a non-linear explicit dynamic model of CFFTs was developed using the commercial software ANSYS Autodyn. This model was verified using the experimental impact and blast test results and used to conduct a parametric study. The results of these investigations indicated that CFFTs were particularly suitable for blast and impact resistant applications, as their geometry diffracted blast waves and the addition of the tube increased their energy absorbing capacity significantly giving them additional strength and ductility. The tube also confined and protected the concrete core and simplified construction.

Abstract:
In this study, we examine strain localization and failure initiation in cylindrical aluminum tubes subjected to radial impulse loading. This thesis is divided into two parts: the first part explores strain localization in aluminum 6061-T6 tubes undergoing radial expansion. An electromagnetically induced body force is used to expand a total of six tube specimens with varying body force intensities. The experimental response of the tube specimen is obtained by capturing images at different times of the expansion via a high-speed camera and conical mirror. A time history of the tube radius and global hoop strain is acquired by fitting the images of the tube with best fit circles using an iterative least-squares approach. For one specimen digital image correlation is implemented in addition to the circle fitting as a means of tracking the local true strain with time. Postmortem observations of the tube specimens reveal a localization pattern different than those found in previous studies that examined aluminum 6061-O tubes. An argument is made that Joule heating and thermal softening contribute to the unique localization pattern. Two numerical models, with differing magnitudes of thermal softening, are constructed to understand the observed localization. At the end of the chapter, proposals for future investigations are presented. The second chapter is devoted to buckling and fracture of an aluminum 7075-T73 tube exposed to a compressive impulse. A numerical model is constructed to analyze the development of fracture nucleation and propagation. Element failure is modeled with the Johnson-Cook damage criterion. Fracture in the walls of buckled cylindrical tubes appears to be a topic not addressed in previous literature. Nodal data and contour plots of the model are used to construct a general case for the response mechanism leading to fracture. Numerical results are compared to previous experimental investigations. Finally, proposals for future experimental examinations of fracture in buckled cylindrical tubes are provided.

Abstract:
The goal of this work is to investigate methods to utilize small scale shock tube testing as a screening procedure for the development of primary blast lung injury protective concepts. For this analysis it is critical to understand and appropriately relate the performance of the material system when challenged in a shock tube test to the material performance under full scale explosive testing. Measurement techniques with shock tubes and explosive tests were used to evaluate shock loading of materials and subsequent stress wave transmission in relation to injury criteria identified in the literature. The materials tested included soft and rigid ballistic materials and foam. Shock tube experimentation was performed with a single, flush pressure sensor mounted behind materials. A full scale test device was created that could be used to obtain pressure measurements under a protective material concept during full scale explosive testing. The device was a Modified Blast Test Device (MBTD) of cylindrical shape with pressure sensors mounted flush to the surface on a circle around the device’s circumference. Pressure measurements without materials and behind materials were gathered in all test scenarios for comparison. The pressure data were used to analyze peak pressure, specific impulse, dP/dtmax, normalized work and acoustic wave transmission. Results of the full scale experimental effort are compared with shock tube results.

In this paper, elastoplastic post-buckling behavior of cylindrical tubes under axial compression is studied by using finite element method. In our study, the effects of tube geometries and strain hardening characteristics on high strain concentrations in circumferential direction εθ which arise at the vertex of outward wrinkles are investigated. It is found that the maximum value of εθ depends on the thickness-to-radius ratio t/R and the nondimentional hardening coefficient Eh/E, and independent of the length-to-radius ratio L/R. In addition, in order to evaluate the maximum strain εθ,max, the effects of tube geometries and strain hardening characteristics on the deformed shapes of folding wrinkles are also discussed.

Abstract:
Sandwich structures are used in many applications in which they are subjected to blast loading due in-air or underwater explosions. In an early phase, the response is dominated by the propagation of waves through the thickness of the sandwich structure which can result in severe damage to the core and debonding. At a later stage, the response if dominated by the overall bending of the structure. A thorough analysis shows that existing plates and shell theories cannot predict the early phase response and that a separate analysis in needed. The behavior of sandwich structures under blast loading depends on the type of core used and the properties of these cores. Constitutive equations and failure criteria will be discussed. We compare the mechanical properties of several types of core: foam, honeycomb, lattice, and corrugated cores. Models with various levels of complexity are developed and to determine the different types of behavior observed during blast loading of sandwich structures. The study of submerged structures subjected to underwater blasts is of particular interest in this study and both evacuated and fluid-filled structures are considered. The complex interaction of the shock wave with a cylindrical or spherical shell is analyzed using a ray tracing approach that accurately predicts the many wavefronts observed during experiments.

Abstract:
The protection of structures under impact loading often necessitates the need for energy absorbers; devices designed to absorb the impact energy in a controlled manner and hence, protect the structure under consideration. Thin-walled tubes are widely used as energy absorbers in various vehicles and moving parts. The objective of the present study is to investigate the energy absorption characteristic of tubes with corrugations in different geometries, in lateral direction. In order to produce corrugations, an innovative solution is introduced. Corrugations can be very easily generated on the surface of cylindrical aluminum tubes by stamping method. Corrugations with different wavelengths and amplitudes can be produced by this method. Experimental tests are conducted to study the effect of changing corrugation geometry (type and amplitude). Quasi-static tests are carried out whose results for lateral compression show that tubes with corrugation have a higher mean crushing force and this force is directly proportional to number of corrugations and their amplitude. Moreover, it is observed that corrugated tubes can absorb approximately four times more energy than tubes without corrugations, in the same size and weight. Finally, considering the experimental tests, corrugated tubes are shown to be more effective in lateral direction as an energy absorber, and they also exhibit desirable force-deflection responses which are important in the design of energy absorbing devices.

Strain growth is a phenomenon observed in the elastic response of containment vessels subjected to internal blast loading. The local dynamic response of a containment vessel may become larger in a later stage than its response in the earlier stage. To further study the mechanism of strain growth, the effect of structural dimensions on strain growth of cylindrical vessels subjected to internal blast loading is thoroughly investigated in this paper. The dynamic response characteristics of eight cylindrical shells with different lengths and thicknesses are studied by finite element software LS-DYNA. It is shown that the structural dimension is a dominant influencing factor of strain growth.

Abstract:
Strain growth is a phenomenon observed in the elastic response of containment vessels subjected to internal blast loading. The local dynamic response of a containment vessel may become larger in a later stage than its response in the earlier stage. In order to find out the possible mechanisms of the strain growth phenomenon, the natural frequencies and mode shapes of various vibration modes in cylindrical shells with different boundary conditions are obtained theoretically and numerically. The dynamic elastic responses of cylindrical shells subjected to internal blast loading are studied by theoretical analysis and finite element simulation using LS-DYNA. It is found that strain growth in cylindrical containment vessels is mainly caused by linear modal superposition and nonlinear modal coupling. The effects of the reflected blast shock waves and structural perturbation are discussed. The proposed theory for the strain growth mechanisms may guide the safe design of cylindrical containment vessels.

Full text
Abstract:
The interactions between internal blast loading and dynamic elastic response of a containment vessel are studied in this paper. The blast loading history is proposed to be divided into three periods, i.e. the primary-shock period, the shock-reflection period and the pressure-oscillation period. It is shown that the initial response of the containment vessel is determined by the peak overpressure and duration of the primary-shock. However, during the shock-reflection period, the response of the containment vessel may be influenced by the shock reflection in the vessel, especially when the dominant frequency of the shock reflection is close to the dominant response frequency of the vessel, and the reflected shock pressure is coupled with the vessel response. During the pressure-oscillation period, the dynamic loading is mainly the oscillation of the internal pressure due to the oscillatory volume change of the vessel, which couples dissipatedly with the vibration of the vessel leading to reduced vibration amplitudes. These fundamental features in the elastic response of containment vessels are demonstrated through an elastic circular ring (or an infinite-length cylindrical shell), which are applicable to other containment vessels.
