By combining the "thickness gradient criterion" and FEM, the FLD of sheet metal can be calculated when the tensile properties is available.

将厚度梯度准则与有限元方法相结合，可在已知薄板单拉性能参数的条件下计算获得其成形极限图。

Based on the study of features of sheet metal parts and Zero Thickness Hypothesis, a new mechanism of naming and identifying topological entities of a feature model is proposed in this paper.

本文在对钣金件特征研究和“零厚度”假设的基础上，提出了一种钣金件拓扑元素命名和辨别的新方法。
