本文依据板料异性性质的正交性,以几种符合正交特性的函数对一些材料的试验数据进行了拟合和对比,并与现有的异性模型进行了比较。结果表明,以形式为 A=A(?)_p+A_2cos2_α+A_4cos4_α的简单函数描述板料的单向拉伸性能的异性情况,是足够准确的。
Based on the orthogonality of the opposite sex of sheet metal, this paper fits and contrasts the experimental data of several materials with several orthogonal functions, and compares them with the existing heterosexual model. The results show that it is accurate enough to describe the anisotropy of sheet uniaxial tensile behavior with a simple function of the form A = A (?) _p + A2cos2_a + A_4cos4_a.
