It is well known that fretting fatigue promotes crack initiation and propagation in structural components, thus causing the failure of mechanical systems. Nowadays, many palliatives such as shot peening are used in order to prevent such ruptures. Nevertheless, when such treatments are applied, the fatigue assessment of the component becomes more complex. In the present paper, a methodology implementing the critical plane-based criterion by Carpinteri et al. for fretting fatigue is employed in order to estimate both endurance strength and fatigue life of Al 7075-T651 alloy shot-peened specimens subject to partial slip fretting fatigue loading.

Abstract
It is well known that fretting fatigue promotes crack initiation and propagation in structural components, thus causing the failure of mechanical systems. Nowadays, many palliatives such as shot peening are used in order to prevent such ruptures. Nevertheless, when such treatments are applied, the fatigue assessment of the component becomes more complex. In the present paper, a methodology implementing the critical plane-based criterion by Carpinteri et al. for fretting fatigue is employed in order to estimate both endurance strength and fatigue life of Al 7075-T651 alloy shot-peened specimens subject to partial slip fretting fatigue loading.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
