A rectangular finite element for analysing composite multilayered shallow shells in statics, vibration and buckling

This paper presents a new 32-degree-of-freedom finite element of multilayered composite, moderately thick, shallow shells. The element is a four-node C 1 rectangular element and is built from standard interpolations but with a new kind of kinematics which allows us to exactly ensure the continuity conditions for displacements and stresses at the interfaces between the layers and the boundary conditions at the upper and lower surfaces of the shell
