摘要：

A finite length Yoffe crack with specified anti-plane shear displacements in an infinite strip made by isotropic functionally graded material (FGM) is studied. Based on exponential variation of the shear modulus and the mass density in FGM, both stress and displacement fields are derived by means of the Fourier-transform method and dual-integral equations. The relationships between the dynamic stress intensity factors, crack moving-velocity, graded parameter and crack length are analyzed. The solution can be reduced to the case of dynamic problems in isotropic homogeneous materials, and shows identical results as well.
