Gradient plasticity with diffuse boundary derived from continuum mixture theory
2007 (English)In: Computational Plasticity - Fundamentals and Applications, COMPLAS IX, 2007, no PART 2, 643-646 p.Conference paper (Refereed)
A mixture theory is used to derive a nonlocal plasticity model. The plastically deforming body consists of a solid skeleton and a liquid in a mixture. Macroscopic yielding is assumed for the solid and the yield function will depend on the presence of liquid from the submitted momentum supply. A microstructural assumption for the momentum supply will give a dependence of derivatives of effective plastic strain. Some room is given to discuss the possible extension and location of the plastic boundary.
