Abstract
The purpose of this present work is to study the arc-shaped interfacial cracking problem in a hollow cylinder that consists of an inner orthotropic dielectric layer and an outer functionally graded piezoelectric layer. Based on the method of variable separation, the problem is reduced to a Cauchy singular integral equation, which is solved by the Lobatto-Chebyshev quadrature technique. Numerical results of the stress intensity factor are obtained and the effects of geometrical and physical quantities on the fracture parameter are surveyed in details.
