Abstract:
In the first part of my talk, I will present a hybrid data-physics driven reduced-order homogenization (dpROH) approach for efficient analysis of fiber reinforced composites. The dpROH improves the accuracy of the physics-based approaches, but retains its unique characteristics, such as interpretability and extrapolation. In the second part of my talk, I will present a hybrid data-physic driven computational framework for high-volume resin transfer molding (HV-RTM) of fiber reinforced composites. Due relatively high speed of resin flow and significant convective effects, the hybrid data-physics drive approach efficiently solves the nonlinear steady-state Navier-Stokes equations rather than the linear Stokes equations commonly adopted for the simulation of classical resin transfer molding processes.
