| 摘 要： | 热轧冲压板开裂现象是一种板材料力学性能各向异性的表现。本文由该材料的微观织构取向变化分析造成板开裂的内在原因,根据能够准确描述塑性各向异性的材料模型,模拟了冲压板开裂圆件成型过程,由其变形分布和应力分布探讨开裂机理。

| Abstract: | It's a kind of phemonemon of anisotropic material to crack hot rolled drawing sheet. The thesis analyzes the inner cracking reason for the hot rolled sheet based on texture orientation transformation, simulates the forming process of drawing sheet by the Barlat-Lian anisotropic yield criteria, and discusses the cracking mechanism in the deforming and stress distribution. |
