Abstract

The dynamic plastic behaviour of circular conical shells subjected to lateral distributed loading is investigated. The intensity of the loading is assumed to follow the form of the rectangular impulse. The material of shells is an ideal perfectly plastic material obeying the square yield condition and the associated flow law. For determination of maximal residual deflections an approximate method of mode form motions is developed. Keywords: plasticity, impact loading, conical shell.
