摘要
根据塑性成形过程中体积不变和弯曲过程的平截面假设以及mises屈服准则,建立了线性强化材料应力微分平衡方程组,然后解出其应力中性层所在的位置,并进行了讨论。
According to the assumption of unchanged volume during plastic forming process and plane section during bending process and mises yield criterion,stress differential balance equation for linear strain-hardening material is set up to find the stress neutral layer position and discussion is performed.
