取铅和铝作试样,进行了剪断过程的平面应变试验。前一种材料很好地满足一般塑性理论中没有加工硬化的假设,同时有效地模拟热剪断(由于铅的再结晶温度在室温以下),而用后一种材料可直接看出加工硬化的影响。
Take lead and aluminum as a sample, the plane shear test of the shear process. The former material well satisfies the assumption that there is no work-hardening in the general plastic theory and effectively simulates thermal shearing (due to the recrystallization temperature of lead below room temperature), whereas the latter material shows the effect of work-hardening directly .
