以弹塑性理论为基础，从弯曲矫直与压扁成形的分离力学模型入手，建立了计算压扁力的独立理论体系，并通过C程度计算，其结果与计算机实测动态曲线相吻合。
Based on the elasto-plastic theory, an independent theoretical system for calculating the crushing force is established, starting from the separation mechanics model of straightening and crushing, and calculated by C degree. The result is in good agreement with the measured dynamic curve of computer.
