Mixed Petrov-Galerkin methods for the Timoshenko beam problem
A new mixed Petrov-Galerkin method is presented for the Timoschenko beam problem. The method has enhanced stability compared to the Galerkin formulation, allowing new combinations of interpolation, in particular, equal-order stress and displacement fields. The methodology is easily generalizable for multi-dimensional Hellinger-Reissner systems.
