Abstract
This paper presents a new C1 81-degrees-of-freedom triangular Materiallyfinite element for geometrically and linear elastic multilayered composite, moderately thick plates. The element has six nodes and is of triangular shape. It is based on a new kind of kinematics and built from Argyris interpolation for bending, and Ganev interpolation for membrane displacements and transverse shear rotations. This kinematics allows to exactly ensure, the continuity conditions for displacements and transverse shear stresses at the interfaces between layers of a laminated structure and the boundary conditions at the upper and lower surfaces of the plates. The representation of the transverse shear strains by cosine functions allows to avoid shear correction factors. The element performances are evaluated on some standard tests and also in comparison with an exact three-dimensional solution for a sandwich plate in statics and dynamics.
