Abstract
A finite element asymptotic analysis for determining the lower bound d ynamic buckling estimates of imperfection-sensitive structures under s tep load of infinite duration is presented. The lower bound dynamic bu ckling loads and the corresponding displacements are sought in the for m of asymptotic expansions based on the static stability criterion and they can be determined by solving numerically (FEM) several linear pr oblems with a single nonsingular sub-stiffness matrix.
