Abstract

The damage occurring during plastic deformation is studied in two coppers with similar matrices but containing two different distributions of particles. The damage is quantified by measurement of the relative density change along two different strain paths: uniaxial tension and equibiaxial expansion. This damage leads to different apparent rheological parameters (work-hardening index) for the two materials, the matrices of which are considered to have similar rheological parameters. This apparent mechanical behaviour is characterized by the forming-limit diagram of the materials studied.
