On the Use of Drilling Degrees of Freedom to Stabilise the Augmented Finite Element Method

The augmented finite element method (AFEM) embeds cracks within solid elements. These cracks are modelled without additional degrees of freedom thanks to a dedicated static condensation process. However, static condensation can induce a lack of constraint problem, resulting in singular stiffness mat...
