为了发挥多晶材料潜力,扩展其应用领域,有必要对织构的形成机理及规律进行研究,而织构的计算模拟恰是进行上述工作的有效手段之一。Taylor曾经指出,晶体中只要有五个滑移系同时开动晶体即可产生任意应变。据此,Van Houtte等采用线性规划原理模拟计算了面心立方金属的冷轧织构。为使模拟更符合晶体形变滑移机理,本文引入临界滑移系开
In order to exploit the potential of polycrystalline material and expand its application fields, it is necessary to study the formation mechanism and rule of texture, and the simulation of texture is just one of the effective means to carry out the above work. Taylor once pointed out that crystals can generate any strain as long as there are five sliding systems that simultaneously activate the crystals. Accordingly, Van Houtte et al. Calculated the cold-rolled texture of face-centered cubic metal using the linear programming principle. In order to make the simulation more in line with the mechanism of crystal deformation slip, this paper introduces the critical slip system to open
