Numerical studies on dynamic pulse buckling of FRP composite laminated beams subject to an axial impact

摘要

The dynamic pulse buckling response of slender fiber-reinforce plastic (FRP) composite laminated beams, having initial geo- metric imperfections, subjected to an axial impulse is simulated by the finite difference method. The primary objective of this study is to study the effect of several parameters with the consideration of the beam's transverse inertia, transverse shear deformation and the cross-section's rotational inertia on the formulation of the beam. It is also desired to identify a parameter by which one can predict the onset of dynamic pulse buckling.
