通过改变升温速度等因素控制颗粒状聚碳酸酯的塑化过程，首次在不破坏材料连续性的条件下制成中间带孔的光塑性实验模拟试件。采用更为符合大塑性变形的Ｅｕｌｅｒ坐标系，对带孔洞圆柱体的镦粗过程进行光塑性分析，得到了孔洞的闭合形式及邻域应变分布等结论。 By changing the heating rate and other factors controlling the plasticization process of granular polycarbonate, for the first time without deteriorating the continuity of the material under the conditions of the hole with a hole in the optical and plastic experimental simulation specimen. The Euler coordinate system, which is more in line with the large plastic deformation, is used to conduct the plastic-plastic analysis of the upsetting process of a cylinder with holes. The conclusion of the closed form of holes and the distribution of the adjacent strain are obtained.
