“…That may lead to struc tural transformation and/or destruction of the mate rial [4][5][6][7]. Therefore, to determine the operational properties of inhomogeneous materials, we need to investigate the stress and strain that arise within indi vidual inclusions as a function of their composition, structure, shape, and concentration, as well as the magnitude and character of the external perturbation [8,9]. In particular, the limiting strength of the inho mogeneous materials must be determined [4,10].…”
