摘要：

An updated finite element method with large degrees of freedom for studies of the stressed-strained state sandwich cylindrical shells, is discussed. Two types of natural-curvature finite elements are being developed for load-carrying layer and for filter in order to model the stressed-strained state of the sandwich cylindrical shell. The developed model allows structures possessing variable stiffness parameters and various types of boundary conditions and loads to be calculated. The stress concentration in structural components including regions of local loads and fixations and other stress zones also can be successively studied on the basis of this model.
