用光塑性法定量计算了普通平板间镦粗圆柱体 ( H0 /D0 =2 )内部应力场。结果与定性物理模拟、数值模拟及刚塑性力学模型的拉应力理论相吻合。
The internal stress field of upset cylinder (H0 / D0 = 2) was calculated by using the plasticity method. The results coincide with the theories of tensile stress of qualitative physical simulation, numerical simulation and rigid-plastic mechanical model.
