Fracture Mechanics of Functionally Graded Materials

Exact solutions of isotropic viscoelastic functionally graded Kirchhoff plates

“…[15]), and generalized to inhomogeneous materials by Shapery in [16]. It is know that the correspondence principle may not hold for functionally graded materials [17]. We consider the class of isotropic functionally graded viscoelastic materials with relaxation moduli in separable form in space and time.…”
