Abstract

The article deals with the analysis of structures made from anisotropic nonlinear elastic materials. A variation of the deformation theory of plasticity by G.A. Geniev was chosen as theoretical basis for the analysis. The article introduces the method of finding the limit load of a structure made of an anisotropic nonlinear elastic material in the state of plane stress. The analysis was carried out with the help of ANSYS software package. A special subroutine UserMat developed by the authors enables the user to specify a model in accordance with the basic theory of material behavior.
