Cover Story: This paper presents a fully convolutional neural network-based model that is capable of predicting stress fields over both the polymer and fiber components, substantially reducing the time required to evaluate the mechanical response of fiber-reinforced composites. The network predicts the stress field in 2D slices of tomography images of a fiber-reinforced polymer specimen. The trained model accurately captures stress distributions, especially around fibers, from microstructure images. Predictions take seconds on a laptop, compared to 92.5 hours for full finite element simulations on a high-performance cluster, offering a promising approach for fast structural analysis and damage site identification in fiber-reinforced composites.
