Abstract

A theoretical study of the dynamic buckling of geometrically imperfect transversely isotropic columns under axial compressive pulse is presented. The analysis includes transverse shear deformation as well as translational and rotational inertia terms. The effects of transverse shear rigidity are investigated for various pulse frequencies, ranging from quasi-static to impulsive compressive loads. An appropriate dynamic buckling criterion is defined and utilized, and the corresponding buckling results are compared with those for isotropic columns and classical beam theory. The results show that for isotropic columns the classical theory predicts accurately the buckling strength of columns to dynamic pulse buckling. However, for columns with low transverse shear rigidity, some buckling loads predicted by the refined theory are as low as almost half of those predicted by the classical theory.
