摘要
文章通过ABAQUS对不锈钢拉伸过程进行模拟,发现压边处应力无明显变化,应力随着变形的增大从顶部到底部增加,底部和侧边边缘处应力最大达238 MPa;结合不锈钢单向拉伸实验和多向拉伸模拟仿真对不锈钢拉伸过程进行研究,表明不锈钢多向拉伸实验结果表面光滑、壁厚均匀、无凹凸和起皱现象,拉伸效果良好。
In this paper,the tensile process of stainless steel was simulated by ABAQUS.It was found that the stress at the blank holder didn’t change significantly.Besides,the stress increased from the top to the bottom with the increase of deformation,and the maximum stress at the bottom and side edge was 238 MPa.The stainless steel tensile process was studied by conducting the uniaxial tensile experiments and multi-directional tensile simulation of stainless steel.The results showed that the surface of stainless steel was smooth,the wall had uniform thickness,and there weren’t concave,convex or wrinkle phenomena.Therefore,the tensile effect is desirable.
