摘要

To study elasto-viscoplastic constitutive equations of any material it is necessary to compare them with results from laboratory tests. Because viscoplastic effects of metals and alloys are often observed at high temperature it is in general only possible to perform rather simple tests. Usually these are tension and compression tests of single specimens, which in numerical applications can be modelled as truss elements. In the following some numerical tests to examine static and dynamic behaviour of elasto-viscoplastic bars are proposed.
