Abstract
The program is designed for numerical evaluation of effective elastic characteristics of inhomogeneous (heterogeneous) materials subjected to preliminary loading in a three-dimensional case. Effective elastic characteristics are estimated in a linear formulation in the form of a generalized Hooke's law describing a linearly elastic anisotropic material. For preliminary loading, geometric nonlinearity is taken into account (i.e., as a result of it, finite deformations may occur in the material). The assessment of effective properties is carried out by solving a number of boundary value problems of elasticity theory on a representative volume of heterogeneous material. These problems are solved by the calculation kernel of small deformations "CAE - Fidesys" using the finite element method (FEM).
