Abstract
The overall response of heterogeneous viscoplastic materials is obtained using self-consistent schemes with the local response governed by convex flow potentials. The tangent model, originally proposed by Molinari et al is reviewed and extended and a discussion of the nonlinear inclusion problem is presented. A new general formulation of the self-consistent scheme is proposed and algorithms of calculations are suggested.Keywords
