Analysis of complex variable processes of elastic-plastic deformation by means of the hierarchical consistency of material models

Boris Melnikov, Artem Semenov


A multimodel analysis of the elastic-plastic behavior of materials and structural components under complex non-proportional variable loading is considered. The multimodel elastic-plastic analysis is based on the developed library of elastic-plastic models and a system of criteria allowing the selection of adequate models. A unified form of material model description is given intended for the efficient finite element implementation. Efficiency of the multimodel analysis is illustrated considering several examples.
