摘　　要：用应力函数法分析了双向拉伸的应力分布,建立了臂上开缝十字形试件双向拉伸试验的有限元模型,使用大型通用有限元软件ANSYS8.0对十字形双向拉伸试验进行模拟及分析,并对其结构尺寸进行优化设计.模拟结果表明,试件中心区域的应力分布是均匀的,当缝宽为0.2 mm时,其不均度最接近于1.With the method of Stress Function, this paper analyzes the distribution of stresses of biaxial tensile and builds the finite element model of biaxial tensile test of cruciform specimens with slots on arms. With the big general software ANSYS8.0, this paper simulates Biaxial tensile test and optimizes the cruciform specimen shape. The results show： the distribution of stresses in the central region of specimen is uniform, the degree of non- uniform approximates to 1 when the gap is 0.2 mm.
