Abstract:

Abstract This paper presents the key outcomes derived from a series of experiments and numerical simulations aimed at understanding how carbon fibre reinforced polymer (CFRP) retrofitted cylindrical steel tubes respond to localised external blast loads. The blast tests were conducted using a ballistic pendulum on both as-received and retrofitted tubes, employing various configurations of CFRP retrofitting. The as-received mild steel cylindrical tubes had an outer diameter of 101.6mm, a wall thickness of 2.0mm, and spanned a length of 400mm. The cylindrical steel tubes were retrofitted with CFR

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

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.

Abstract:

Recently, a concrete-filled steel tube confined with fiber-reinforced polymer (FRP) has become a hot research issue as a new type of structure. These studies mainly focus on its static performance and seismic and impact behaviour, with little research on its blast resistance performance. In this study, the dynamic response of concrete-filled steel tube columns confined with FRP under blast loading was investigated. Numerical analysis was implemented using multimaterial ALE method in the finite element analysis program LS-DYNA. The proposed numerical model was validated by the SDOF result and a

Abstract:

Extensive research focus had been given to sacrificial sandwich panels to mitigate the effects of blast loads. This is due to their ability to distribute the load and absorb a significant portion of the blast energy. This paper studies the behavior of sacrificial sandwich mild steel panels of axially oriented octagonal tapered tubular cores subjected to near-field impulsive blast. The deformation behavior and several assessment parameters consisting of the peak force, stroke efficiency, energy absorption and core efficiency were investigated using validated finite element analysis.

Abstract. This contribution presents the investigation of energy absorption mechanism of metal tubes and composite-wrapped metal tubes subjected to a diametric deformation via an expansion process. In the experiments, the expansion of the tubes was performed under quasi-static loading using a conical-cylindrical expansion die. The experimental results are repeatable and thus reliable. An extensive finite element analyses and experimental investigation were carried out in parallel. Both two-dimensional and three-dimensional finite element models were created based on the actual experimental geo

Abstract:

Three-dimensional fully coupled simulation is conducted to analyze the dynamic response of sandwich panels comprising equal thicknesses face sheets sandwiching a corrugated core when subjected to localized impulse created by the detonation of cylindrical explosive. A large number of computational cases have been calculated to comprehensively investigate the performance of sandwich panels under near-field air blast loading. Results show that the deformation/failure modes of panels depend strongly on stand-off distance. The beneficial FSI effect can be enhanced by decreasing the thickness of fro

Abstract:

When determining the mechanical properties of ring specimens, a feature of a uniaxial (standard) loading scheme is that the method of applying a load to a specimen is somewhat remote from that to which the pipe walls can be subject in real operating conditions, in particular, these are tubes of fuel element shells. As an alternative loading method, the method of strain of an ring specimen on a cylindrical rod was considered and tested. By compressing the cylindrical rod from the ends, which in this case expanded and exerted pressure on the inner walls of the ring specimen in the radial directi

Abstract:

Experimental research and numerical simulations of the structural response to shock waves with pulse durations of hundreds of milliseconds, or even seconds, are extremely challenging. This paper takes typical single-layer and sandwich cylindrical shells as the research objects. The response rules of cylindrical shells under long-duration blast loadings were studied. The results show that when the pulse duration is greater than or equal to 4~5 times the first-order period of the structure, the maximum response of the structure tends to be consistent, that is, the maximum response of the cylindr

Abstract:

Our research investigated the energy absorption characteristics of chiral auxetic lattices filled cylindrical composite tubes subjected to a uniaxial and lateral quasi-static load. The lattice structures were manufactured using a 3D printing technique. Carbon fiber composite tubes without filler material were initially subjected to uniaxial and lateral quasi-static crushing load. The same types of experiment were then performed on chiral lattices and chiral lattices filled composite tubes. For the different cases, the load–displacements curves were analyzed and the specific energy absorption (
