Buckling analyses of composite laminate skew plates with material nonlinearity

Interaction of damage failure and post-buckling behaviour of composite plates with cut-outs by progressive damage modelling

“…It is found that the plate thickness influences significantly the interaction between damage evolution, initial buckling load and the post-buckling response. Comparisons of the analysis results of the present PDM methodology with existing experimental results from [9] have shown a good correlation. Poisson's ratio in the (ij) direction, -X,Y,Z strength in the x-, y-, z-direction respectively, N/m 2 S ij shear strength in the (ij) direction, N/m 2 2.…”

“…[4,5]. The buckling behaviour of a damaged composite plate has also been considered in [6][7][8][9][10]. However, the simple ply-discount method and twodimensional stress analysis utilized in [6,7], are not capable of accurately predicting the influence of interlaminar stresses.…”

“…Buckling analyses of several types of composite plates have been performed [8][9][10], in order to examine their buckling resistance, as well as their post buckling behaviour. Although the damage criticality due to delamination under buckling is investigated, damage evolution in the plates has not been modelled and the different damage modes have not been discussed.…”

Dual-axis buckling of laminated composite skew hyperbolic paraboloids with openings

“…Pandit et al [13] used an improved higher-order zigzag theory to present buckling behavior of sandwich laminates. An FE buckling analysis of laminated rhombic plates having material nonlinearity, including the Tsai-Wu failure criterion and a nonlinear in-plane shear formulation, is carried out by Hu and Lin [14]. A C 0 FE formulation using HSDT has been presented by Pradyumna and Bandyopadhyay [15] to study buckling behavior of laminated composite conoids and hyparshell.…”

Buckling Analysis of Smart Material Plates Using Higher Order Theory

“…The results obtained by them are verified with numerical solution available in the literature. Hsuan-Teh Hu et al [2] has carried finite element buckling analysis under uniaxial compressive loads for composite laminate skew plates, by employing a nonlinear constitutive model, which includes a non linear in-plane shear formulation and Tsai-Wu failure criterion for fiber composite laminate materials. They have presented the influences of plate aspect ratio, plate skew angle and laminate layup on buckling resistance of composite laminated skew plates.…”
