Shear driven crack arrest investigation under compressive state: Prediction of fretting fatigue failure of aluminium strands
Source abstract
Abstract
Abstract Fretting fatigue crack propagation in aluminium strands was investigated through experimental tests and FEM simulations. Fretting fatigue tests revealed that crack nucleation predictions are not sufficient to fully predict the total strand failure, and crack arrest conditions may be reached for nucleated cracks. The geometry of arrested cracks was characterized and used to perform simulations using FEM in order to dedude Stress Intensity Factor (SIF) distributions along the crack front. These results showed that even in a fully compressive state, cracks are still able to propagate to a certain extent, and a mode II SIF threshold has been proposed.
