ABSTRACT

The paper deals with the analysis of failure initiation in shells made of Fiber Metal Laminates (FML). The elastic material law for orthotropic lamina is stated accounting for asymmetric in-plane stress and strain measures. The asymmetry results from the employed general nonlinear 6-field shell theory where the generalized displacements involve the translation and the proper rotation field. The novelty of the presented results stems from the fact that the membrane strains and stresses are asymmetric.
