Combined use of solid of revolution, thin shell, and interphase elements for analysis of cylindrical shells

Abstract

Near the boundaries of shells, thin shell theories cannot always provide a satisfactory description of the kinematic situation. This imposes severe limitations on simulating the boundary conditions in theoretical shelI models. Here an attempt is made to overcome the above limitation. Three-dimensional theory of elasticity is used near boundaries, while thin sheH theory covers the major part of the shell away from the boundaries. Both regions are connected by means of an "interphase element." This method is used to study typical static stress and natural vibration problems.
