✦ Synopsis

Buckling of axially compressed elastic}plastic beams is discussed. The load is applied instantaneously and remains unaltered during the motion. The e!ect of stress waves travelling along the beam is taken into account. It is assumed that the material of the beam has linear-strain hardening. A method of solution, based on the Galerkin technique, is proposed; this method is applicable to an arbitrary number of degrees of freedom. Numerical examples are presented.

Dynamic axisymmetric buckling of circular cylindrical shells struck axially by a mass is studied in order to clarify the initiation of buckling and to provide some insight into the buckling mechanism as a transient process. It is assumed that the material is elastic±plastic with linear strain harden
