通过DEFORM软件进行轧制模拟，模拟大尺寸钨板坯的轧制方式造成的损伤因子和应变的区别。模拟实验发现，单向轧制的损伤严重区域主要分布在坯料侧面边缘处，易发生裂纹；交叉轧制时损伤严重区域比较均匀的分布在坯料四周，由损伤累积而产生韧性裂纹的倾向性小；交叉轧制板材在轧制方向的应变曲线会到达一个“最高值”后会下降到上一道次横向应变，形成“最小值”，交叉轧制时两个应变最大值的差值比单向轧制的小。

DEFORM software was used to simulate the difference of damage factor and strain caused by rolling mode of large size tungsten slab. The simulation results show that the severe damage area of unidirectional rolling is mainly distributed at the side edge of billet, which is prone to crack. In cross rolling, the severe damage area is evenly distributed around the billet, and the tendency of ductile cracks caused by damage accumulation is small. The strain curve of the plate in the rolling direction will reach a "maximum value" and then decrease to the last transverse strain, forming a "minimum value". The difference between the two maximum strains in the cross rolling is smaller than that in one-way rolling.
