Node-to-segment and node-to-surface interface finite elements for fracture mechanics [PDF]
, 2016 The topologies of existing interface elements used to discretize cohesive cracks are such that they can be used to compute the relative displacements (displacement discontinuities) of two opposing segments (in 2D) or of two opposing facets (in 3D ...

Finite Fracture Mechanics at elastic interfaces
International Journal of Solids and Structures, 2012 AbstractIn the present paper we provide a method to determine the load causing delamination along an interface in a composite structure. The method is based on the elastic interface model, according to which the interface is equivalent to a bed of linear elastic springs, and on Finite Fracture Mechanics, a crack propagation criterion recently proposed ...
