The research on the Very High Cycle Fatigue (VHCF) response of materials has gained increasing attention in the last few years. Indeed, the fatigue life of components has significantly increased and can exceed one billion of cycles in many industrial sectors, such as, automotive and aerospace sectors. Accordingly, to ensure a safe fatigue design and the structural integrity of components produced through traditional and additive manufacturing (AM) processes, experimental tests investigating also the VHCF life range should be carried out. In this chapter, a comprehensive analysis of the VHCF response of AM parts is carried out. Literature results obtained by testing AlSi12, AlSi10Mg, AlSi7Mg, Ti6Al4V, IN718, and 316L steel specimens are analyzed. The factors affecting the VHCF response of AM parts and the influence of defects are highlighted and discussed for the analyzed material. The main objective of this chapter is to provide the reader with an overview on the state of the art of the research on the VHCF response of AM parts, of utmost interest among the scientific community.

Abstract
The research on the Very High Cycle Fatigue (VHCF) response of materials has gained increasing attention in the last few years. Indeed, the fatigue life of components has significantly increased and can exceed one billion of cycles in many industrial sectors, such as, automotive and aerospace sectors. Accordingly, to ensure a safe fatigue design and the structural integrity of components produced through traditional and additive manufacturing (AM) processes, experimental tests investigating also the VHCF life range should be carried out. In this chapter, a comprehensive analysis of the VHCF response of AM parts is carried out. Literature results obtained by testing AlSi12, AlSi10Mg, AlSi7Mg, Ti6Al4V, IN718, and 316L steel specimens are analyzed. The factors affecting the VHCF response of AM parts and the influence of defects are highlighted and discussed for the analyzed material. The main objective of this chapter is to provide the reader with an overview on the state of the art of the research on the VHCF response of AM parts, of utmost interest among the scientific community.File | Dimensione | Formato | |
