Orthotropic rotation-free basic thin shell triangle. (English) Zbl 1166.74042
Summary: We develop a methodology for geometrically nonlinear analysis of orthotropic shells using a rotation-free shell triangular element. The method is based on the computation of strain and stress fields in the principal fiber orientation of the material. Details of the definition of the fiber orientation in a mesh of triangles and of the general formulation of the orthotropic rotation-free element are given. The accuracy of the formulation is demonstrated in examples of application.
