SOLID ELEMENTS WITH ROTATIONAL DOFS BY EXPLICIT HYBRID STABILIZATION

Two brick elements equipped with Allman's rotation are presented. Stra in energy of both elements is sub-integrated by the second order quadr ature which gives rise to the hourglass mechanisms. Inasmuch as Allman 's rotation is employed, the elements are also plagued by the equal-ro tation mechanisms. Variational functional containing independently ass umed stress, displacement and rotation is employed to formulate the st abilization devices for the elements. Computational cost of the elemen ts is reduced by incorporating the explicit hybrid stabilization techn ique. Popular numerical benchmarks are studied and the present element s are found to be competitive to other state-of-the-art elements.
