Efficient concurrent multiscale damage analysis of woven composite structures based on data-driven reduced order model

Concurrent multiscale damage analysis is still a challenge in woven composite structural level due to its extremely high computational cost. In this paper, a novel efficient concurrent multiscale framework for woven composite structures is proposed based on data-driven reduced order model, and the multiscale damage behavior of 4-H satin weave carbon/carbon composites is investigated using this framework. The elastic properties of yarn are predicted using the information from fibers and matrix. The mesoscale anisotropic damage behaviors of the open hole plate under uniaxial tension are simulated using this framework. The simulation results have good agreement with the experiment.
