Abstract Plane elasticity problem of a simply supported laminated cylindrical shell with imperfectly bonded orthotropic or isotropic layers subjected to static loading is considered. Imperfect bonding of layers is modeled by a linear uncoupled interfacial law which relates the tangential and normal interfacial tractions to the sliding and opening displacement jumps at the interface. The problem is solved in closed form through a matrix formulation and novel explicit expressions are presented for displacements and stresses. The expressions are valid for shells with any numbers of layers under plane-strain or plane-stress conditions, can be readily applied to generate benchmark solutions and perform parametric analyses. The expressions recover the solution to the plane elasticity problem of plates for the limiting case of shells with infinite curvature. Results are presented in tabular and graphical forms for a sandwich shell.
