In this study, the Outwater-Murphy specimen is modeled using a finite element superelement approach. Stress analysis is carried out to find the distributions of stresses at the intersection of the fiber end and the hole edge. Micromechanics analysis is employed to determine the homogenized mechanical properties of the superelement embedded in the 3D model. Stress distributions for neat resin specimens determined from 2D and 3D models are in good agreement. The 3D stress analysis shows that the debonding process of the fiber near the hole edge occurs under radial tension (σ_r).
