Streszczenie:

A theoretical solution method for the in-plane vibration characteristics of the plate with cutouts is proposed in this paper. The energy principle in conjunction with the Rayleigh–Ritz solution technique is adopted for the theoretical modeling of the in-plane vibration of the structure. The energy functions for the plate with cutouts are established by subtracting the energies of the cutout domains from the total energies of the whole plate. To ensure continuity over the entire solution domain, the in-plane displacements are composed of two-dimensional standard Fourier series and supplementary functions. The in-plane eigenmodes of the plates with different square cutouts are compared with the results obtained from the finite element method (FEM), with good agreements. The influences of the cutouts on the in-plane vibration characteristics of the plates with cutouts are investigated by varying the number, size, and position of the cutouts.

The aims of this study are to obtain experimental data on the crushing of stiffened square tubes, and to develop a simple analytical expression for predicting the mean crushing strength of stiffened plates making up a plated structure. A series of axial crushing tests in a quasistatic condition was carried out on thin-walled square tubes which were composed of four identical panels. Specimens with longitudinal and/or transverse stiffeners, including unstiffened specimens, were tested, varying dimensions of plate and stiffener. The effective crushing length and the mean crushing strength of the test specimens were investigated. It was concluded that a longitudinally stiffened plate could reasonably be replaced by an unstiffened plate with equivalent plate thickness. Based on this approach, a simple expression for the effective crushing length and the mean crushing strength of stiffened plates was derived.

Streszczenie:

Based on the classical thin plate theory, this paper proposes new sets of enriched basis functions for in-plane and out-of-plane displacements of square plates that can yield admissible functions for the Ritz method using the moving least-squares (MLS) approach. These admissible functions display the discontinuities of displacement and slope across a crack; give the correct singularity order for the stress resultants at the crack tips; and enhance the Ritz method’s ability to recognize the existence of an internal crack in a plate. To confirm the validity of the proposed approach, convergence studies were performed on the buckling loads and vibration frequencies of plates with central horizontal cracks, and the results obtained agree closely with the published ones as well as those generated by the commercial finite element software. To demonstrate the importance of including all the in-plane stress resultant components in the analysis, the effects of different in-plane stress resultant components on the buckling loads and vibration frequencies of simply supported center-cracked square plates under uniaxial uniform loading were investigated. The present approach was further employed to study the effects of cracks’ lengths, orientations, and locations on the buckling loads and frequencies of cracked square plates under different boundary conditions and in-plane loading conditions.

Abstract Many Mechanical structures are manufacture by using plates. However Harmonic Analysis of plate is growing research subject in today’s era. In the present research paper vibrational response of simply supported square plate with uncertain parameters are studied. In designing any real life mechanical system uncertainty phenomenon plays vital role. Thus it becomes important to study the effect of uncertainty for different frequency domain in mechanical system. In present research work square plate as structural element is selected. On this plate mass, stiffness and both collectively mass and stiffness uncertainty are taken. The plate boundary condition selected is simply supported. For determining the plate dynamic response FEM tool is used. While doing harmonic analysis the behavior of all uncertain parameters plates are compare with bare plate. In the FRF plot of plate with stiffness uncertainty, it is found that it has drastic changes in dynamic response. Thus this shows that uncertain parameters have adverse effects and it changes the dynamic behavior of the structure.

Streszczenie:

Cutouts are commonly found in aerospace, ships, and marine structures, which have a great influence on mechanical properties such as stress concentration, natural frequency, and structural load-bearing performance of the structure. In this study, buckling behaviors of a square plate with a circular flanged cutout at the center are explored numerically, aiming to address the influence of different cutout parameters on the elastic and elasto-plastic buckling behaviors of the perforated plate. The flanged-perforated plate is subjected to uniaxial compressive loads, and the four edges are simply supported in the out-of-plane direction. The influence of various cutout parameters on the elastic and elasto-plastic buckling behaviors of the perforated plate is examined through a series of buckling analysis. In addition, structural weight reduction of the uniaxial compressed perforated square plates is carried out under the constraint of the elastic buckling stress of the plate structure. The findings indicate that different cutout parameters have a significant impact on the buckling performance of the plate. Perforated plates with flanging exhibit higher buckling strength than those without flanging, and variations in plate geometric parameters (such as the plate slenderness ratio and cutout radius ratio) are associated with increases in elastic buckling stress and elasto-plastic ultimate strength. The results of this paper can provide references for the design of flanged-cutouts in engineering.

Streszczenie:

The high-strength-to-weight ratio and corrosion resistance properties of glass-fiber-reinforced polymer (GFRP) composites makes them potentially well-suited for application in ship structures, bridges and off-shore oil platforms. These structures are often formed by stiffened plates and are subjected to axial load and out-of-plane load. Cutouts and openings are provided in the plates for access and maintenance. The main objective of this study was to examine the buckling behavior of GFRP-stiffened composite plates with square cutouts under a combination of axial and out-of-plane load up to failure. Four blade-stiffened composite plates without a cutout and four with square cutout were fabricated with stiffeners as a continuous layup of the flange plate using glass fiber and epoxy resin. The initial geometric imperfections were measured, and plate imperfections (Δx), stiffener imperfections (Δsy) and overall imperfections (Δsx) were calculated from the measurements. All fabricated-stiffened composite plates were tested up to failure. The finite element model was developed in ANSYS software and validated with the experimental results. It was observed that GFRP-stiffened composite plates failed by stiffener compression/stiffener tension mode of failure. The presence of out-of-plane loads and cutouts reduced the axial load carrying capacity of the stiffened composite plates.
