Tell Me More


The course outcomes for ME 561: Engineering Plasticity state that students will “Use physical models to describe the plasticity behavior of materials in 2D (LO1.1, 1.3)”. The model will allow students to visualize and interact with a model which shows them the basics of plasticity theory.

Project Information

When applying a force to a material a stress is developed. In response to that stress there may be some deformation (change in shape) or strain the in that material. Stress and strain can be graphed together. Within this graph there are two main regions: the elastic region where a material may deform when a force is applied but will resume its original shape when the material is unloaded and the plastic region where deformation within the material is permanent and when the material is unloaded the effects of the stress applied will be evident. The focus here will be on the plastic region. In this region material deformation is permanent, history dependant and highly non-linear.
