功能梯度材料多层结构界面裂纹的热弹性分析
Thermoelastic Analysis of Functionally Graded Layered Structures with An Interface Crack
摘要
Abstract
The temperature and thermal stresses around a partially insulated crack in a functionally graded sandwich structures is obtained based on the theory of Fourier heat conduction.The materials properties are assumed to vary as an exponential function of thickness direction.By using Fourier transforms technique,a system of singular integral equations related to the temperature and the thermal stress field are obtained and solved numerically.Numerical results are given to reveal the influence of the material graded parameters and the partially thermal conductivity on the temperatures along the crack plane and the thermal stress intensity factors (TSIFS).关键词
