Abstract
ABSTRACT In this paper, we focus our attention on geometrically non linear behaviour of multilayered plates. For this purpose, a high order plate model is used which exactly ensure both 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 plate. Based on this kinematics, a six node C1 triangular finite element is developed, using a conforming finite element method and a displacement approach. The Argyris interpolation is used for transverse displacement and the Ganev interpolation is used for membrane displacements and transverse shear rotations. A set of linear and non-linear tests is presented in order to show the efficiency of this finite element.
