Identification of elastic properties of individual material phases by coupling of micromechanical model and evolutionary algorithm

The paper is devoted to an inverse problem of identification of individual material phases properties in dependence of known effective properties. In order to solve the identification problem, combining evolutionary algorithm with Mori-Tanaka method is proposed. In particular, the study focuses on a three-phase composite and takes experimental results from literature as an input data to analysis. The original contribution of this paper is a new identification strategy involving a resultant error that represents the uncertain character of both experimental data and model predictions. The new approach is demonstrated by performing several analyses with various assumptions.
