Probabilistic framework for fatigue life assessment of notched components under size effects
Ding Liao,Shun-Peng Zhu,Shun-Peng Zhu,Shun-Peng Zhu,Behrooz Keshtegar,Guian Qian,Qingyuan Wang +6 more
TL;DR: A probabilistic framework is proposed for fatigue life assessment of notched components under size effects, in which the Smith–Watson–Topper damage parameter is utilized to characterize the multiaxial stress state at the notch tip.
Journal ArticleDOI
Probabilistic modeling of uncertainties in fatigue reliability analysis of turbine bladed disks
TL;DR: A general framework for fatigue reliability analysis is developed by coupling the Latin hypercube sampling with FE analysis to describe the combined effects of multi-source uncertainties to show that geometrical uncertainty matters in structural fatigue reliability.
Journal ArticleDOI
Comparison of four heuristic regression techniques in solar radiation modeling: Kriging method vs RSM, MARS and M5 model tree
TL;DR: In this paper, four different heuristic regression methods including Kriging, response surface method (RSM), multivariate adaptive regression (MARS) and M5 model tree (M5Tree) have been investigated for accurate estimating of solar radiation with different input data.
Journal ArticleDOI
Probabilistic modeling of fatigue life distribution and size effect of components with random defects
Yang Ai,Shun-Peng Zhu,Shun-Peng Zhu,Ding Liao,José A.F.O. Correia,Carlos D.S. Souto,A.M.P. De Jesus,Behrooz Keshtegar +7 more
TL;DR: In this article, a probabilistic model to account for the influence of manufacturing defects on fatigue life, based on size and position of those defects, is presented, where a correction factor is developed by modeling the damage mechanism of surface initial cracks with Weibull distribution.
Journal ArticleDOI
Adaptive conjugate single-loop method for efficient reliability-based design and topology optimization
TL;DR: The numerical experiments demonstrate that the convergence capability of the proposed adaptive conjugate single-loop approach (AC-SLA) is significantly superior to the PMA, RIA, and SORA.
