Fiber-reinforced polymer matrix composites (FRPMCs) often undergo intra-laminar fiber-matrix fracture, commonly known as splitting, under tensile loading. Numerical modeling faces challenges in predicting this failure mode and its effect on a macroscopically homogenized model. We propose an effective two-scale modeling approach that integrates the micromechanics 2-concentric cylinder (2CYL) analytical technique to capture pre-peak nonlinearity and the 3D orthotropic smeared crack approach (SCA) to simulate post-peak softening behavior. By using typical 3D finite elements, we represent a homogenized ply that explicitly considers matrix fracture concerning the ply angle orientation. We demonstrate the method's capability by predicting grip-to-grip longitudinal splitting in a 00 ply, mixed-mode matrix cracking in a 450 ply, transverse matrix cracking in a 900 ply, and the failure of the laminate comprising these plies. Our results indicate that our proposed approach closely aligns with experimental findings.
