This work covers the topic of micromechanical modeling of the elastic and fatigue behavior of short glass fiber reinforced thermoplastic composites (SFRTs). A novel algorithm extracts microstructural data from x-ray micro-computed tomography scans. Analytical homogenization schemes are studied and used to predict elastic properties, while a high cycle fatigue model using the Two-Step scheme incorporates damage variables for fibers and matrix, predicting fatigue limits.
