title = "Three-dimensional cohesive element formulation for delamination modeling",
abstract = "This work examines cohesive element techniques for modeling delamination within a finite element method framework. Cohesive elements maintain compatibility between plies of a composite laminate where delaminations can occur. The formulation of cohesive elements for three-dimensional models is detailed. The constitutive behavior for cohesive elements is described in terms of traction-separation behavior. A user-defined cohesive element is coded for implementation within the ABAQUS commercial finite element software. User-defined cohesive element damage traction-separation behavior is tested against ABAQUS built-in cohesive elements and results from numerical verification tests of the user-defined cohesive element are shown. The major benefit of having a user-defined element is the ability to customize mixedmode damage models with various novel traction-separation laws.",
