【Abstract】 Upsetting of circular cylinder between ordinary plat platens is studied through the optical plasticity.The photoplasticity and incremental theory are joined together to quantitative calculate the stress of upsetting circular cylinder initially.The result of simulation corresponds to the results of qualitative physical simulation.The tension stress theory of a rigid-plastic mechanical model on upsetting circular cylinder is intensified.更多还原
