Abstract 3D failure criteria for laminated fibre-reinforced composites, based on a physical model for each failure mode and considering non-linear matrix shear behaviour, are developed. Special emphasis is given to compression failure. The physical model for matrix compression failure is based on the Mohr–Coulomb criterion and also predicts the fracture angle. For fibre kinking, an initial fibre-misalignment angle is considered to trigger failure, due to further rotation during the compressive loading. The plane where the kinking takes place is predicted by the model, as well as the kink-band angle. Applications are presented that validate the model against experimental data.

Mechanical behavior of unidirectional fiber-reinforced polymers under transverse compression: Microscopic mechanisms and modeling (2007, methodology): “The angle a formed between the failure plane and the through-thickness (or perpendicular to the in-plane loading) direction is slightly above 45� and typical values reported are in the range 50–56� [23, 21 ,24].”
Three-dimensional invariant-based failure criteria for fibre-reinforced composites (2015, methodology): “…Schürmann (1998, 2002) for transverse failure37 are often used by the composites’ research and design communities, with38 several other theories appearing as extensions to these criteria (Dávila and39 3 Camanho, 2003; Dávila et al., 2005; Pinho et al., 2005, 2006; Catalanotti et40 al., 2013).”
