功能梯度压电底层中两共线双裂纹对 SH 波的散射
Scattering of S H-w ave from the tw o collinear cracks in the substrate of functionally graded piezoelectric materials
摘要
Abstract
The problem of SH-wave scattering from two collinear cracks in the substrate of functionally graded piezoelectric composite materials is discussed . Under the permeable boundary conditions , the problem is reduced to the solution of a pair of dual intergral equations by using the Fourier transforms , which are reduced to a Fredholm integral equation by the Copson method . In the end , numerical results show the effect of the frequency of wave , the half length of the crack and material gradient on the right normalized stress intensity factor .关键词
