RISA Modified Closed Form Energy Based Framework for Axial Isothermal Mechanical Fatigue Life Assessment for Aluminum 6061 T6
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the present investigation, the applicability of a previously developed closed form energy based framework to predict low cycle fatigue (LCF) life of aluminum 6061T6 was extended from room temperature to elevated ...
A Robust Optimization Technique for Calculating Scaling Coefficients in an Energy Based Fatigue Life Prediction Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The energybased lifing method is based on the theory that the cumulative energy in all hysteresis loops of a specimens' lifetime is equal to the energy in a monotonic tension test. Based on this theory, fatigue life can ...
Prediction of Nonlinear Evolution of Fatigue Damage Accumulation From an Energy-Based Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An energy-based framework is developed for welded steel and AL6061-T6 for assessment of nonlinear evolution of fatigue damage accumulation along fatigue life. The framework involves interrogation at continuum using a newly ...
A Comparison of Constitutive Equations for the Energy Based Lifing Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Alternatives to quasistatic and dynamic constitutive relationships have been investigated with respect to a previously developed energybased fatigue lifing method for various load profiles, which states: the total strain ...
Measurement of Hysteresis Energy Using Digital Image Correlation With Application to Energy-Based Fatigue Life Prediction
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: A modified experimental method using digital image correlation (DIC), a noncontact optical method for measuring full-field displacements and strains, is used to interrogate accumulated fatigue damage for low and high cycle ...
