A phantom node formulation with mixed mode cohesive law for splitting in laminates (2009, methodology): “One way to implement this is to model the split with interface elements (see Wisnom and Chang 2000; Yang and Cox 2005; Hallett and Wisnom 2006b; Jiang et al. 2007). In that case, however, cracks may only appear between elements, which may complicate mesh generation. Moreover, the location of cracks ”

Comparison of open hole tension characteristics of high strength glass and carbon fibre-reinforced composite materials (2008, background): “[17] studied scaling effects for quasi-isotropic stacking sequences and found that sub-laminate scaled SOHT decreased with increasing specimen size, but conversely, SOHT increased with increasing specimen size for blocked stacking sequences.”
