Crack surface interference under cyclic mode I and steady mode II loading

The sliding contact mechanism proposed in Part I of this publication is quantitatively analysed with the assumption of rigid asperity and Coulomb friction. A discrete step-wise iteration program, with a capability to cope with opening, sticking, bottom touching, down and uphill sliding, is developed to solve the crack surface interference under cyclic mode I and steady mode II loads. The effects of plastic/oxidation-induced crack closure...
