Fatigue assessment of a riveted shear splice based on a probabilistic model

Fatigue Damage Analysis of Offshore Structures using Hot-Spot Stress and Notch Strain Approaches

“…Simplified fatigue method proposed in the same standard is used in the proposed fatigue procedure presented in Figure 2. The second proposed fatigue methodology based on notch (local) strain approach uses the Neuber rule and Ramberg-Osgood description as well as the Coffin-Manson relation with objective to evaluate the strain amplitude and number of cycles [12,13].…”

Structural reliability analysis and uncertainties‐based collaborative design and optimization of turbine blades using surrogate model

“…To improve the performance of blades, it is necessary to analyze the coupling mechanism between shockwave and boundary layer . Many valuable studies have been proposed to perform this analysis by means of numerical simulations combining with physics of failure modeling . Among them, Wang et al utilized a reliability index strategy and proposed an uncertainty‐based optimization model for the structure design problem with bounded uncertain information.…”

“…9 Many valuable studies have been proposed to perform Nomenclature: X R , continuous random variable; M XR ξ ð Þ, the moment generating function of X R ; K XR ξ ð Þ, the cumulant generating function of X R ; f XR x R ð Þ, the probability density function of X R ; e ξ, the saddlepoint; ϕ(•), the standard normal probability density function of X R ; Φ(•), the standard normal cumulant generating function of X R ; X, the vector of local design variables; X S , the vector of shared design variables; Y ji , the vector of coupling variables which are the output of discipline j; Y ij , the vector of coupling variables which are the output of discipline i; J, the compatibility constraint; Pr(•), the reliability constraints this analysis by means of numerical simulations combining with physics of failure modeling. [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25] Among them, Wang et al 10 utilized a reliability index strategy and proposed an uncertainty-based optimization model for the structure design problem with bounded uncertain information. Correia et al 11 proposed a generalization probabilistic fatigue model which can include multiaxial loading conditions and mean-stress effects.…”

Probabilistic framework for multiaxial LCF assessment under material variability

“…In order to quantify LCF life variability, most of available researches [5], [17], [37], [38], [48]- [50] focused primarily on obtaining the lifetime distribution from variation under given loading conditions as well as, the variation in the crack formation and crack growth rates.…”
