Kurzfassung englisch:
The paper presents a shell element based unit cell approach for numerical homogenization of fiber reinforced textile laminates. The modeling strategy is set up within the framework of the Finite Element Method. Multilayer laminates comprising equal weaves are considered and all constituents, i. e. the tows as well as the unreinforced matrix pockets are discretized by shell elements only which are coupled appropriately. A study on the effective extensional laminate-shell stiffnesses is presented and a typical approach to deal with multiple layers found in the literature, i. e. distinguished out-of-plane boundary conditions applied to a single layer, is discussed. Additionally, non-linear simulations are conducted and delamination phenomena are investigated.
