| Abstract |
The present paper deals with plane deformation problems (εz=0) concerned with elastoplastic deformation
of a space with a cylindrical cavity in the case where
the load is given either at infinity or on the cavity surface. It is assumed that the material obeys the relations of the theory of flow with isotropic hardening and the von Mises plasticity condition. The effects of the elastic compressibility (Poisson's ratio) and the coefficient of linear hardening on the stress-strain state are studied. The influence of the linear hardening is shown to be small, while that of the elastic compressibility is shown to be quite significant. |
