A new concept for the construction of locking-free finite elements for bending of shear deformable plates and shells, called DSG ('Discrete Shear Gap') method, is presented. The method is based on a pure displacement formulation and utilizes only the usual displacement and rotational degrees of freedom at the nodes, without additional internal parameters, bubble modes, edge rotations or whatever. One unique rule is derived which can be applied to both triangular and rectangular elements of… CONTINUE READING
