摘要 在本文中，分析了瞬态热载荷条件下功能梯度压电材料条（FGPM 条）包含垂直于 FGPM 条和均质层之间界面的裂纹的问题。裂纹面应该是完全绝缘的。假设材料属性与距界面的距离呈指数关系。使用拉普拉斯和傅立叶变换，热机电问题可简化为奇异积分方程，并可进行数值求解。计算嵌入裂纹和边缘裂纹的应力强度因子。还包括裂纹接触问题的结果。
ABSTRACT In this article, the problem of a functionally graded piezoelectric material strip (FGPM strip) containing a crack perpendicular to the interface between the FGPM strip and a homogeneous layer is analyzed under transient thermal loading condition. The crack faces are supposed to be completely insulated. Material properties are assumed to be exponentially dependent on the distance from the interface. Using the Laplace and Fourier transforms, the thermoelectromechanical problem is reduced to a singular integral equation, which is solved numerically. The stress intensity factors of embedded and edge cracks are computed. The results for the crack contact problem are also included.
