Abstract
This paper introduces the strain-rate effects in the analysis of dynamic buckling of a perfectly plastic column. The corresponding differential equation of dynamics is deduced. The expressions of half-wave length of buckling mode, critical load and time of buckling are obtained. Discussion on the strain-rate effect on the plastic dynamic buckling of a column is presented. The results of this paper are compared with those of the theory and experiment in [4].
