摘要

在过去的一个世纪里，在许多行业中，如金属成形工业，对复杂载荷下金属的韧性损伤和断裂进行预测已经成为一项重要的工作。关于伤害机制，最经典的模型之一是GTN模型，该模型最初由Gurson提出，后来由Tvergaard和Needleman进行了改进。改进是通过在Gurson模型的屈服函数中引入等效空隙体积分数f和另外两个参数q1和q2来实现的。

Prediction of FLD using Abaqus and Gurson Model for Simple Flat Spacemen

In the past century, in many industries, such as, metal forming industry, it has been important to predict ductile damage and fracture of metals under complex loadings. Regarding damage mechanics, one of the most classical models is the GTN, which was originated from Gurson and later enhanced by Tvergaard and Needleman. The inprovement was achieved by introducing an equivalent void volume fraction f and two more parameters called q1 and q2 into the yield function of Gurson’s model.
