Modeling of localization using Nash variational formulations: The extended damage mechanics
Engineering Fracture Mechanics(2021)
摘要
•This paper proposes an extension of the lumped damage mechanics for 2D solids.•Numerical extensometers characterize the thickness of localized bands in 2D solids.•A modified constant moment tringle is proposed including hinge-lines with softening.•The proposed model circumvents the mesh size dependency and scale effect.
