英文摘要	The influences of die parameters on shear strain were investigated by using two-dimensional finite element simulation. New formulas of shear strain were proposed. According to the results of formulas, the shear strain showed a linear dependence on the difference between internal and external fillet radius and the slope was determined by the intersection angle. The simulation results indicated that the velocities of the points from different zones were different in the specimen and the motion trajectories of different points did not follow geometrical laws. The influences of the average velocity and the motion trajectory on shear strain were incorporated in the formula to calculate the shear strain produced during equal channel angular pressing process. The reliability of simulation results has been partially validated by experiments.; Fundamental Research Funds for Central Universities of China [HEUCF20151002]; SCI(E); 中国科技核心期刊(ISTIC); ARTICLE; zhangdiantao@hrbeu.edu.cn; lili_heu@hrbeu.edu.cn; 10; 1020-1027; 23
