Fracture and fatigue of the surface layer of layered media due to adhesive sliding contact
Engineering Fracture Mechanics(2020)
Abstract
•Fracture and fatigue of an elastic layer on an elastic-plastic substrate due to adhesive sliding contact.•Effect of critical parameters on fracture and fatigue crack initiation and crack growth direction.•Shear-to-tensile mode transition of fatigue crack growth in the layer.•For similar tensile and shear fracture toughness, the out-of-plane tensile mode controls layer fracture.•For similar tensile and shear fracture toughness, both in-plane shear and out-of-plane tensile modes control layer fatigue.
