Stress Analysis for an Infinite Strip Weakned by Periodic Cracks

  • 摘要: 作出了周期裂纹削弱的无限长板条的应力分析.假设这些裂纹均在水平位置,又板条承受 y方向的拉伸力p.此时边值问题归结为一个复杂混合边值问题.发现,对此问题言,特征展开变分原理方法 ( eigenfunction expansion variational method,简称为EEVM)是非常有效的.研究了裂纹端的应力强度因子和T-应力.从拉伸力作用下的弹性变形考虑,开裂板条可等价于一不开裂的正交异性板条.还分析了等价正交异性板条的弹性性质.最后给出了算例和数值结果.
