WebJun 15, 2024 · The formulation for the traction-separation law was based on the constitutive behavior of a process zone of a void spacing thickness that followed elastic-plastic relation till the onset of softening. The onset of softening was taken to depend on the stress-state characterized by the triaxiality parameter. WebThe fracture toughness of metals and other ductile materials is dependent on their thickness. The toughness is highest when plane stress conditions exist at the crack tip, and this occurs when the material is thin (typically less than several millimetres).
