A COUPLED THERMO-CHEMO-MECHANICAL REDUCED-ORDER MULTISCALE MODEL FOR PREDICTING RESIDUAL STRESSES IN FIBRE REINFORCED SEMI-CRYSTALLINE POLYMER COMPOSITES

International Journal for Multiscale Computational Engineering, vol. 18, pp. 519–546

Abstract

We study residual stresses and strength induced by a manufacturing process of carbon fiber reinforced semi-crystalline polymer matrix composites and subsequent mechanical loading. Reduced-order homogenization (ROH) approach has been employed to address tremendous computational complexity stemming from analyzing complex thermo-chemo-mechanical processes at multiple scales. The proposed reduced-order two-scale thermo-chemo-mechanical model has been verified against a high-fidelity model based on the direct first-order computational homogenization (FOCH) approach. It has been shown that for problems considered herein the ROH offers a speed-up in terms of CPU time over FOCH of three orders of magnitude.
