Finite element analyses were performed to investigate theoretically the effects of in‐plane and out‐of‐plane eccentricities, bending or twisting, and thickness nonuniformity on the axial stress and strain variations across the width of off‐axis specimens. The results are compared with measured data and are also used to assess the effects of these eccentricities on the fracture stress of off‐axis fiber composites. Guidelines for detecting and minimizing the presence of eccentricities are described.
