An efficient and locking-free flat anisotropic plate and shell triangular element
We discuss, in a unified manner, the application of generalised decomposition principles and physical lumping techniques in finite element analysis of isotropic and laminated plates and shells. Using physical ideas and basic relations of mechanics, as well as geometrical arguments, we reduce the apparent complexity of the kinematical behavior of such structures by means of assigning rigid-body and straining modes of deformation to an assembly of elements which comprise a compatible kinematical idealization. Subsequently, we apply these assertions to study a flat three-node 18 degrees-of-freedom triangular shell element applicable to the analysis of isotropic and fibre-reinforced laminated composite structures.
