An energy method for rapid evaluation of high-cycle fatigue parameters based on intrinsic dissipation
TL;DR: In this paper, a calculation model of intrinsic dissipation, based on the double exponential regression for the one-dimensional distribution of specimen surface temperature variation, is proposed for rapid evaluation of high-cycle fatigue parameters (i.e., fatigue limit and S-N curve).
Journal ArticleDOI
A new model for fatigue life prediction based on infrared thermography and degradation process for CFRP composite laminates
TL;DR: In this article, a new fatigue life prediction methodology is proposed by combining stiffness degradation and temperature variation measured by InfraRed Thermographic (IRT) camera, which can be used to determine the fatigue limit by using the data of stabilized temperature rising.
