✦ Synopsis

The problem of collinear periodical cracks in an anisotropic viscoelastic plane with surface separation and friction sliding, which is an important model of rock-shear dilation, is considered. In this model, the shear dilation of rock is caused by the upward separation of sliding rough-cracked surfaces, and the rock material is anisotropic viscoelastic. Using the method of Laplace transform an exact solution to this problem is obtained. The stress intensity factors and separation of crack surfaces are also given.
