Abstract

The paper is devoted to the comparative analysis of features of some popular mechanical models of interphase boundaries in metal-ceramic composite materials. We have numerically studied the influence of the parameters of interface models on effective strength, strain-hardening coefficient and ultimate strain of a microscopic composite fragment including adjacent areas of the matrix, inclusions and the interface zone. We have shown that the most "powerful" and flexible mechanical model of an interphase boundary is the model of an "interface shell" with a gradient of mechanical properties.
