33 - Representation of Elasto-plastic Behavior Using Mohrs Circle
Lee, Jae Young
This screen demo shows how Mohr's circles can be used in representing the elasto-plastic behavior in finite element analysis. The transition of stress state from elastic to plastic is illustrated by the image of incremental Mohr’s circles and envelope curve. The characteristics of plastic yield criteria and their significance can also be observed by comparing the Mohr’s circles for the stresses under different criteria.
