Analytical modeling of fatigue crack propagation based on cyclic hardening and a characteristic damage length
(2020)An analytical fatigue crack growth model is developed, which combines effectively a cyclic energy dissipation approach and the strain energy density theory. The model uses cyclic material properties and relies on cyclic ... -
An experimental approach for estimating the effect of heat affected zone (HAZ) microstructural gradient on fatigue crack growth rate in aluminum alloy FSW
(2017)The microstructural gradient of the heat affected zone (HAZ) in aluminum alloy FSW has been simulated experimentally by subjecting the parent alloy to a controlled aging process. The purpose of the simulation is to estimate ... -
Rolling contact fatigue cracking in rails subjected to in-service loading
(2016)Rolling contact fatigue (RCF) is one of the most important failure mechanisms in rails with significant cost- and safety-related implications on the operation of railway systems. In this work, a metallurgical analysis of ...
