Engineering prediction of sheet metal forming thickness and springback

研究了忽略薄板厚度变化对有限元仿真计算时间和计算结果的影响 。

In this paper,it is researched that the calculation time and the simulation result is affected by neglecting of the sheet metal thickness changing in the forming processing.By comparing the calculated results,which are obtained in several different conditions,the paper displays the relationship curve between the critical factors and the springback of the sheet metal.
