Abstract
In the field of continuum damage mechanics (CDM) approaches are suggested to take into account the influence of damage on deformation behaviour. Some of them, like the effective stress concept and the principle of strain equivalence, respectively, are commonly used in the same manner either for elasticity or plasticity. However, the self-consistent embedded cell model, which is suitable for determining global behaviour of composites, is an appropriate tool to verify these assumptions. In connection with the finite element method (FEM) this self-consistent scheme is used to determine the elastic and plastic behaviour of isotropic materials incorporating uniform distributed flows. The influence of flow shape, size and orientation are studied. On the basis of the results obtained, the CDM approaches mentioned above are discussed.
