摘要：

Simultaneous influence of substrate curvature and compliance on delamination of coatings is investigated by modeling of the delaminated part of the coating with a slightly curved cylindrical plate with boundary conditions of the type of elastic clamping. Elongated delaminations located along both axial and circumferential directions are considered for both inner and outer surfaces of a cylinder. Propagation of the above types of delaminations due to their elongation and widening is studied.
