Options of decomposition of tensors of full stresses in modeling the processes of elastic-plastic deformation of auxetic media with cubic symmetry of properties

The paper presents the results of calculations of the elastoplastic deformation of the target using two variants of the decomposition of the total stress tensors into parts, corresponding to the volume strain and shear strain. The processes of elastoplastic deformation of a target made of a single-crystal VZhM8 alloy under shock loading by a steel projectile are simulated. The influence on the results of numerical simulation of the application of two variants of the decomposition of the total stress tensors for the target of a single-crystal alloy VZhM8, possessing auxeticity in the direction of loading, is shown.The paper presents the results of calculations of the elastoplastic deformation of the target using two variants of the decomposition of the total stress tensors into parts, corresponding to the volume strain and shear strain.
