Computer Simulation of Plastic Deformation of Inhomogeneous Material with Elliptic Inclusions Sliding Along Boundaries

The plastic deformation behavior of inhomogeneous materials with elliptic inclusions is studied numerically. A plane model of inhomogeneous material with thin boundary region between elliptic inclusion and matrix is adopted, where the material is assumed to be rigid-plastic. The rigid-plastic solution is important not only for plastic deformation problems with large strain, but also for creep deformation problems through the plastic analogy in the creep analysis. The effects of material parameter and loading conditions are examined and discussed.
