Abstract
One of the most promising advantages with additive manufacturing is the ability to fabricate complex geometries. These geometries can have significant impacts on thermal histories, microstructures, defects, and fatigue behavior. This study aims to investigate the effects of thickness variation on the fatigue life of AM fabricated components subjected to uniaxial loading through the introduction of a novel specimen geometry. The geometry is designed with a constant cross-sectional area and varying thicknesses by changing the diameter, ensuring constant stress throughout the gage section. Results found minimal relationship between the thickness and fatigue behavior for the as-built surface condition.
