Buckling of laminated composite hypars and conoids using a higher-order theory

Abstract: A C 0 finite element formulation using a higher-order shear deformation theory (HSDT) is developed and used to analyse the buckling behaviour of laminated hypar and conoids. Higher order terms in the Taylor's series expansion are used to represent the higher-order transverse cross-sectional deformation modes. The formulation includes Sanders' approximation for doubly curved shells considering the effect of transverse shear. A realistic parabolic distribution of transverse shear strains through the shell thickn… Show more

“…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. Akbulut et al [16] calculated critical buckling loads of composite stepped columns using FEM.…”
