Abstract
In this paper, the viscoelastic fracture of a functionally graded material strip with a crack normal to the gradient direction is studied. The linear elastic crack tip fields subjected to stress load and strain load are obtained with the finite element method. The effects of the crack location, crack length, material gradient index and the loading on the crack tip field are investigated. In addition, the stress intensity factors of the viscoelastic functionally graded strip are obtained with the correspondence principle for the viscoelastic solids.
