Abstract

A general heterogeneous approach to modeling and approximate analytical solution of the problem of single-axis deformation of an elastoplastic spherical shell are used to obtain a law of quasistatic plastic flow for porous metals, which proves to agree well with experimental data on deformation of porous copper and tungsten. In contrast to other known models the proposed flow law is not associated with the corresponding flow surface.
