In Part I of the paper, a hybrid-stress-assumed natural strain eight-node solid-shell element immune to shear, membrane, trapezoidal, thickness and dilatational lockings has been developed. Moreover, the element computational cost is reduced by enforcing admissible sparsity in the #exibility matrix.

This paper presents an eighteen-node solid element for geometric nonlinear analysis of shells. Starting from a stressresultant approach, a modified generalized laminate stiffness matrix is developed. The matrix resolves not only thickness locking but also some abnormalities encountered in laminate a
