RISA Probabilistic Micromechanical Code for Predicting Fatigue Life Variability: Model Development and Application
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper summarizes the development of a probabilistic micromechanical code for treating fatigue life variability resulting from material variations. Dubbed MICROFAVA (micromechanical fatigue ...
A New Tool for Design and Certification of Aircraft Turbine Rotors
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper summarizes recent enhancements to a probabilistic damage tolerance software code, DARWINTM, that can be used for design certification of aircraft jet engine titanium disks/rotors that ...
Probabilistic Treatment of Crack Nucleation and Growth for Gas Turbine Engine Materials
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The empirical models commonly used for probabilistic life prediction do not provide adequate treatment of the physical parameters that characterize fatigue damage development. For these models, ...
