Abstract：

According to the choice theory of sheet cutting shape based on deforming ample degree,the choice process of sheet cutting shape based on deforming ample degree was given.The choice evaluation of sheet cutting shape based on deforming ample degree was studied.The plane strain cracking and deforming ample degree showed on the long side straight-wall were evaluated,using one truck back-wheel cover drawing as an example.Distribution of elongation transform and stress was given.Combined with the goal specimen of sheet strain,compared values of experiment and theory for the given example's cracking force were presented.
