Journal ArticleDOI
Development of a novel vibration-based fatigue testing methodology
TL;DR: In this paper, a topological design procedure, incorporating a finite element model, was proposed to produce the shape of the sample necessary to achieve the required stress state/pattern, and a forced vibration-based fatigue procedure for conducting the high cycle fatigue experiments with variable-amplitude loading.
Journal ArticleDOI
The Evaluation of the Damping Characteristics of a Hard Coating on Titanium
TL;DR: In this article, the damping characteristics of magnesium aluminate spinel, MgO+Al2O3 (mag spinel) on titanium plates from an experimental point of view were evaluated.
Journal ArticleDOI
Relating porosity to fatigue failure in additively manufactured alloy 718
TL;DR: In this article, the porosity created during the additive manufacturing process is investigated, and its influence on performance is quantified with respect to the processing-structure-property-performance (PSPP) framework.
Journal ArticleDOI
Bending fatigue life characterisation of direct metal laser sintering nickel alloy 718
Onome Scott-Emuakpor,Jeremy Schwartz,Tommy George,Casey Holycross,Charles Cross,Joseph C. Slater +5 more
TL;DR: In this article, a vibratory high cycle fatigue (HCF) assessment of direct metal laser sintering (DMLS) Ni Alloy 718 from two suppliers is presented.
Journal ArticleDOI
Development of an Improved High Cycle Fatigue Criterion
TL;DR: In this paper, an integrated computational-experimental approach for prediction of total fatigue life applied to a uniaxial stress state is developed, which consists of the following elements: (1) development of a vibration based fatigue testing procedure to achieve low cost bending fatigue experiments and (2) developing of a life prediction and estimation implementation scheme for calculating effective fatigue cycles.
