Long-term open-hole compression strength prediction of composite laminates

  • 摘要: 加速试验方法(ATM,Accelerated Testing Methodology)基于复合材料基体的黏弹性特性,根据时间-温度叠加原理,用较高温度下的短期强度预测较低温度下的长期强度.对应变不变量失效理论(SIFT,Strain Invariant Failure Theory)进行改进,采用微观的最大应变准则判断纤维的拉伸和压缩失效.通过基体动态力学分析(DMA,Dynamic Mechanical Analysis)试验得到基体的储能模量控制曲线和时间-温度平移因子.通过不同温度下单向板拉伸、压缩试验得到破坏应变,根据时间-温度叠加原理采用基体的时间温度平移因子,构建SIFT临界值的控制曲线.采用应变不变量失效理论和加速试验方法(SIFT/ATM)结合渐进损伤分析,对准各向同性开孔板压缩长期强度进行了预测,并对破坏过程进行了模拟,分析了纤维和基体的失效过程.计算与试验结果吻合较好,证明了该方法的适用性.
