Abstract

Plastic flow in two-phase fibre composites during axially symetric deformation is modelled assuming homogeneous deformation of the fibres of the harder phase and inhomogeneous flow in the softer matrix. The distribution of flow between fibres and matrix is described by the deformation ratio α which follows from the assumption of minimum deformation work. The main features of the model agree quite well with experimental results obtained in several powder metallurgically prepared two-phase composites.
