Forecasting High Cycle and Very High Cycle Fatigue Through Enhanced Strain-Energy Based Fatigue Life Prediction
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study applies a novel strain-energy based fatigue life prediction method to low cycle fatigue (LCF) data additive manufactured (AM) Inconel 718 round dog-bones, specifically focusing on cycles to failure less than ...
Establishing an Acceptance Criteria for Assessing Fatigue of Additive Repair Processes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Criteria for assessing high cycle fatigue (HCF) capability are important for transitioning additive repair technologies to turbine engines. By studying the fatigue results of two additive repair technologies on Titanium ...
Vibration Fatigue Assessment of Additive Manufactured Nickel Alloy With Inherent Damping
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The fatigue life behavior and internal surface conditions of inherently damped additive manufactured (AM) specimens subjected to vibration bending are under investigation. This study supports research that demonstrated 95% ...
Investigating Discrepancies in Vibration Bending Fatigue Behavior of Additively Manufactured Titanium 6Al-4V
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The vibration bending fatigue life uncertainty of additively manufactured titanium (Ti) 6Al-4V specimens is studied. In this investigation, an analysis of microscopic discrepancies between ten fatigued specimens paired by ...
