On the formulation and implementation of extrinsic cohesive zone models with contact

Variational approach for nonsmooth elasto-plastic dynamics with contact and impacts

“…This should lead to non-convex optimization problems for which it will be necessary to guarantee the existence of solutions and to find robust nonlinear programming algorithms. Finally, a coupling with cohesive zone models for fracture seems quite simple, based on the recent work of Collins-Craft et al (2022). The question of softening behaviors is more difficult because it would require using second gradient models or Cosserat media, but this crucial point could deserve a dedicated development.…”
