The application of the Elasto plastic-damage model is used to describe the ductile fracture model. Few parameters are responsible for ductile damage and its mechanism can be revealed by using Elasto plastic models. An overview of different models is described in this paper. Parameters responsible for high-stress triaxiality and low-stress triaxiality are also described in this paper. The objective of this article is to provide a review of Elasto-plastic damage models, which can be used for prediction of ductile fracture. Stress triaxiality is the ratio between mean stress and equivalent vonmisses stress.
