Stress intensity factors of composite orthotropic plates containing periodic buffer strips [PDF]
The fracture problem of laminated plates which consist of bonded orthotropic layers is studied. The fields equations for an elastic orthotropic body are transformed to give the displacement and stress expressions for each layer or strip.
