Multiple-point constraint applications for the finite element analysis of shear deformable composite beams  Variational multiscale approach to enforce full composite action
Layers are connected using multiple-point constraints at the nodes. Variational multiscale approach is used to identify the numerical error. Full-interaction between the layers could be recovered. Numerical error can be represented by using extra fictitious elements and springs.
