Some solutions to crack growth effects in metallic materials - crack shape progress and plasticity induced crack closure simulation
Original language description
One of the main contemporary challenges being pertinent to the subject given is the prediction of fatigue crack propagation components made of ductile metallic matter. Owing to the high stresses round the crack tip, strips of constantly deformed material occur along the opposite crack faces in the course of the crack growth [1]. These strips contact each other through portion of the loading cycle, yielding a wedge result known as Plasticity Induced Crack Closure (PICC). It is a basic aspect of the mechanics of propagating cracks that clarifies diverse effects referred to the fatigue crack propagation, such as the effect of stress ratio, mean stress and specimen thickness. Moreover, PICC affects the crack shape evolution (CSE), causing a larger growth retardation (wedging effect) close to face surfaces. The matter is an independent analysis of both events PICC and CSE.
