Abstract

Damage processes in structural components are closely related to stress singularities, the simulation of which requires the inclusion of transverse normal strains in the finite-element models. If the shell structure is thick or consists of strongly dissimilar material layers, transverse shear strains are also to be considered in the analysis. In most existing shell models, the deformations mentioned are either totally neglected or not considered at an accuracy level adequate with requirements of the failure analysis. Thus the objective of this contribution is the development of finite shell elements on the basis of higher order kinematic approximations ensuring an arbitrarily accurate prediction of shear deformations and thickness stretching. The final goal is the application of these models to shell problems with stress singularities as well the failure analysis of composite laminates where fiber/matrix cracks are the essential failure mechanisms to be investigated.
