Abstrakt
This work deals with analysis of isotropic or orthotropic girders subjected to transient dynamic loads. Numerical calculations were performed with the finite element method using ANSYS® software. The results of computation were presented as maximum angle of rotation of the girder in a function of the dynamic
load factor, DLF (the ratio of pulse loading amplitude to static critical load). In study it has been taken into account apart from the elastic-plastic range of material with isotropic hardening as well as the strain rate effect described by Perzyna model.
