Transient response of an edge interfacial crack in bonded dissimilar strips with a functionally graded interlayer under an antiplane shear impact

摘要

Highlights?An edge interfacial crack in bonded dissimilar strips with a graded interlayer under antiplane shear impact.?Power-law variations of the shear modulus and mass density of the interlayer.?Dynamic stress intensity factors vs. the material and geometric parameters of the problem.?Effect of mass density ratio in conjunction with that of shear modulus ratio.?Effect of geometric parameters for various material combinations.AbstractThe transient response of an edge interfacial crack in bonded media with a functionally graded interlayer is investigated under the condition of an antiplane shear impact. The graded interlayer is assumed to follow power-law variations of the shear modulus and mass density between two dissimilar, homogeneous semi-infinite strips. Based on the use of Laplace and Fourier integral tran
