English abstract:
The paper presents a plane periodic, shell element based unit cell approach to investigate the non-linear response of fiber reinforced polymer fabrics. Within this approach the tows as well as the matrix pockets are discretized using Finite Elements of shell type only. The interfaces between these constituents are assumed to be perfect and realized bz appropriate couplings. The homogenized tows are modeled by a non-linear constitutive law featuring damage, plasticity and softening. The matrix pockets are modeled as elasto-plastic employing a Drucker-Prager type model. The approach is illustrated by investigating a single layer of 2/2 Twill Weave. Non-linear implicit Finite Element Methods simulations are conducted to highlight the capabilities of the approach.
