COMPUTATIONAL DESIGN OF NONLINEAR STRESS-STRAIN OF ISOTROPIC MATERIALS

The article deals with the problems of numerical modeling nonlinear physical processes stress-strain state structural elements. An elastoplastic medium a homogeneous solid material is investigated. results computational experiments on study process physically deformation isotropic elements three-dimensional structures system one- and double-periodic spherical cavities under uniaxial compression are presented. influence mutual stress concentrators in form cavities, vertically located two horizontally structure Numerical algorithms have been developed for solving made materials, which make it possible to effectively use capabilities computer technology. optimal parameters construction calculation fibrous composite materials using specialized software package determined.
