Abstract
We propose a mixed hybrid 4-node shell elements based on Hu-Washizu principle. Apart from displacements both strains and stress fields are treated as independent fields. The element is derived in the framework of a general nonlinear 6-field shell theory with drilling rotation which is dedicated to the analysis of multifold irregular shells with intersections. The novelty of the presented results stems from the fact that the measures of strains and resultant stresses are asymmetric. With the proposed mixed 4-node element it is possible to use large load steps in nonlinear computations.
