| Abstract: | Based on the basic theory of Elasto/Visco-plasticity, this paper derives some finite element formulas, presents a unified mathematical model and fortran program applicable for elasto/plasticity, elasto/visco-plasticity, creep strength analysis. Calculating examples show that the model can be applied to pertinent practical engineering problems. For convenient application, this paper also gives the selection range of some parameters according to the calculating results and study. |
