Originální abstrakt

The plastic behavior of some polycrystalline metals exhibit the Lode dependence. There are many yield criteria, which are capable of such a description. Nevertheless, these criteria predict wrongly the deformation or the stress state or both in some cases. This paper focuses on the comparison of the deformation predicted by a classical von Mises yield criterion and advanced model, which covers the Lode dependence. The comparison was carried out using the tensile tests of two types of specimens manufactured from the aluminum alloy. The numerical simulations were conducted in the Abaqus/Explicit finite element commercial code and the material models were implemented using the user subroutine.
