| Abstract: | The article described the background in which the G-T model is put forward and the process of development. It also introduced the applications of the G-T model in the analysis of the ductile fracture, and the research status inside and out of the nation. It described the virtues and shortcomings of the G-T model and improved the foreground in the application. The new produced soft wares which based on the G-T model will simulate and predict the process of ductile fracture more exactly. |
