| 摘 要： | 利用有限元法分析方板在单向和双向对角拉伸条件下诱导压应力的变化规律。计算和实验表明,施加横向拉力,实现双轴向拉伸,能明显减小横向诱导压应力及其分布范围,从而抑制皱曲的发生和发展。

| Abstract: | The distribution of transversely induced compressive stresses in the uni-and biaxial diagonal tensile test of square specimen(YBT) is analysed by means of finite element method.The calculation and experiment show that,in the case of biaxial tensile test,transverse loading can obviously reduce the value of compressive stress and its range of distribution,and thus the initiation and growth of wrinkles are restrained. |
