以聚碳酸酯为模型材料, 首次采用三维光塑性方法对连续包覆型腔内金属流动过程进行了模拟实验研究,给出了稳态变形阶段型腔内的三维应变分布。分析了型腔内应变分布的特点,给出了金属在型腔内的流动规律
Taking polycarbonate as a model material, the three-dimensional photoplastic method was used for the first time to simulate the metal flow in a continuous cladding cavity. The three-dimensional strain distribution in the cavity during steady-state deformation was given. The characteristics of the strain distribution in the cavity are analyzed, and the law of metal flow in the cavity is given
