- Abstract
- For the simulation of sheet hydroforming for the shaping of woven fabric reinforced thermo-plastic (FRT) composites, a nonorthogonal
constitutive model was developed based on a homogenization method by considering the microstructures of composites
including mechanical and structural properties of the fabric reinforcement. This model is modified to capture the wrinkling behavior
due to the undulation geometry of the woven structure and shear stiffness at the crossover of the warp and weft yarns of woven FRT
composites. The model was implemented in an explicit dynamic finite element code to analyze the forming behavior of woven FRT
during the stamp thermo-hydroforming process. Wrinkling behavior was investigated based on the application of a counteracting
fluid pressure and changes to the initial blank shape.
