NON-LINEAR FINiTE ELEMENT ANALYSIS OF DYNAMlCALLY LOADED STRUCTURES

Abstract

An effective finite element method has been presented for calculating transient response of dynamically loaded structures. The so-called implicit-explicit algorithm is suitable to analyse geometrically and materially non-linear problems. The analytic integration of Prager's kinematic hardening rule permits the 'exact' calculation of stresses during plastic deformation.
