Abstract: An enhanced eight node solid-shell element formulation is demonstrated. The enhanced strain method is used to alleviate the locking problems. A co-rotational formulation is adopted in the formulation, thus geometric nonlinearity is taken into account by the rotation of the local coordinate system. Several benchmark problems are studied to demonstrate the efficiency of the element.
Keywords: Co-rotational formulation, solid-shell element, the enhanced strain method.
