| 摘 要： | 板料弯曲变形力一般都是根据材料力学方法计算,而滑移线法常用作分析理想刚塑性材料平面变形问题。通过对板料弯曲变形区应力状态分析,利用滑移线理论建立滑移线场,并根据滑移线场推导变形区的应力分布方程。基于变形区应力分布方程计算板料弯曲变形力,进一步对变形力进行修正,修正后的计算结果与根据弯矩求得的结果吻合较好。

| Abstract: | The deformating force of sheet metal bending is generally calculated according to mechanics of materials.However,the plane deformation problem of rigid-perfectly plastic material is often analyzed by the slip-line method.And the paper aims to analyze the stress state of the deforming regions and build the slip-line field based on the slip-line theory.According to the slip-line field,the distribution equation of stress is induced in the deforming regions.The deforming force of sheet metal bending is calculat... |
