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
Multilayer laminates comprising equal weaves are considered and the
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,
the results are discussed, and are compared to approaches found in the
Additionally, geometrically nonlinear simulations are conducted and the results
are compared with experimental tests from literature.
