Micro Abstract:
Organic sheets consist of embedded interwoven rovings in a thermoplastic matrix. Loading results in a finite change of local reinforcement orientations with reversible and irreversible contributions. A constitutive model taking into account the large strain kinematics and damage evolution is presented. Mechanism-based damage formulations in both the reinforcements and the matrix are employed. Numerical examples demonstrate the features of the suggested material model.
