摘要
文章对含I型裂纹的正交各向异性功能梯度材料板沿其板厚的弹性常数表达式呈指数函数变化时的应力-应变场进行分析。从而完整地推导出功能梯度正交各向异性材料板的裂纹尖端应力场、应变场的理论计算公式。
In this article, the fracture analysis on mode I crack of orthotropic functionally gradient materials is studied, under which the elastic constants changed exponentially along thickness of the plate. The calculation functions of the stress and strain fields near crack tip are derived.
