Probabilistic modeling of fiber–matrix interface stresses in short-fiber 3D printed composites using effective field methods Vrije Universiteit Brussel
This study presents a novel probabilistic modeling approach to investigate the impact of interfacial damage between fibers and the matrix on 3D-printed composites. The approach employs effective field methods (EFM) and Weibull statistics and considers an elastoplastic matrix reinforced with short fibers. A new formulation is developed to compute normal and shear interface stresses using the internal stress of each fiber, which is modeled as ...
