PLASTICITY THEORY AND APPLICATION FOR SINTERED POEDER MATERIALS

Abstract

Abstract: The yield condition for sintered powder materials is proposed based on the definite physical concept and stress strain relations are derived in the paper. The strengthening curve of sintered copper is determined by experiment. The following yield congdition for sintered powder materials is constructed from the curve. The relation of deformation load and relative density for closed die forging of sintered copper is analysed with the help of the present theory, and is compared with experimental results.
