Fiber reinforced polymer matrix composites (FRPMCs) often experience intra laminar fiber- matrix fracture, sometimes referred to as splitting, during tensile failure. Numerical modeling issues are related to the prediction of this failure mode and its impact on a macroscopically homogenized model. A very effective two-scale model is shown, which utilizes the analytical technique of the micromechanics 2-concentric cylinder (2CYL) for pre-peak nonlinearity and interfaces with the 3D orthotropic smeared crack approach (SCA) for post-peak softening behavior. Using typical 3D finite elements, a homogenized ply is represented in a way that allows for the explicit capture of a matrix fracture with regard to the ply angle orientation. By forecasting the grip-to-grip longitudinal split in a 00 ply, mixed-mode matrix cracking in 450 ply, transverse matrix cracking in 900 ply, and the failure of laminate comprising these plies, the suggested method's capacity is shown. It is discovered that the predictions made by the suggested approach and the related experimental results accord rather well.
