We develop finite element framework of different length-scales (micro- and mesoscale) in order to study damage mechanism of continuous fiber-reinforced thermoplastic composites. At micro-scale, the size of unit cell (RVE) is determined rigorously by two-point probability function and Hill-Mandell kinematics. Transverse and shear failure in glass/polypropylene at microscale are simulated. Mesoscale models under in-plane tension and out-of-plane (quasi-static indentation) loads are also developed. Strain-rate dependent damage models are proposed in this work. This project is funded by SABIC Europe.
