"Combined Micro- and Macromechanical Considerations of Layered Composite Shells";
International Journal for Numerical Methods in Engineering, 37 (1994), 15; S. 2609 - 2629.

This contribution deals with a computational treatment of the non-linear behaviour of composite sandwich shells with extremely thin face layers and a relatively thick orthotropic core, and multi-layered fiber reinforced polymer (graphite-epoxy) or metal matrix composite shells. Special emphasis is laid on algorithms which allow the consideration of local effects, like face layer wrinkling in sandwich shells and progressive damage or microplasticity in fibre composites, by semi-analytical approaches implemented into a finite element formulation. This leads to the advantage that the shell structure must be discretized only up to an element mesh density which is sufficient for describing the global deformation and stability behaviour.
