Mathematical Modelling of Structurally Inhomogeneous Porous Materials Forming Processes

A mathematical model of the shaping processes of structurally inhomogeneous porous materials has been developed. Generalized relations of the theory of elastic-visco-plasticity for dispersed materials are used for rigid-plastic and elastic-plastic of the material solid phase models. The procedures of projection-grid methods for solving boundary value problems were used. It has been performed in form of step by step calculation. The special algorithm is used to consider some types of plastic deformation, including rigid plastic behaviour, elastic – plastic case and some other rheological behaviour of matrix materials. The algorithm procedures were realized in a form of numerical model. Some elements of this model were implemented in modern finite element software versions. The results of calculations, aimed at manufacturing of main and responsible parts are presented in article.
