A Higher‐Order Multiscale Finite Element Method Based on the Ultra‐Weak Mixed Formulation for 3D Solids
A new version of the multiscale finite element method (MsFEM) for elastic solid bodies, based on the mixed ultra‐weak formulation is presented. The mixed formulation ensures fast stress convergence, while its ultra‐weak variant facilitates the construction of conforming shape functions. Furthermore, the stability gua...
