Conception robuste de structures périodiques à non-linéarités fonctionnelles

Autor: Chikhaoui, Khaoula

L’analyse dynamique des structures de grandes dimensions incluant de nombreux paramètres incertains et des non-linéarités localisées ou réparties peut être numériquement prohibitive. Afin de surmonter ce problème, des modèles d’approxima

Autor: Chikhaoui, Khaoula, Bouhaddi, Noureddine, Kacem, Najib, Ichchou, Mohamed

Publikováno v: Euro-Mediterranean Conference on Structural Dynamics and Vibroacoustics
Euro-Mediterranean Conference on Structural Dynamics and Vibroacoustics, Apr 2017, Sevilla, Spain

International audience; It is known that, when the mechanical coupling between the components is weak, small imperfections in a periodic structure can induce vibration localization. Stochastic analysis of near-periodic coupled pendulums chain is disc

Uncertainty propagation combining robust condensation and generalized polynomial chaos expansion

Autor: Chikhaoui, Khaoula, Kacem, Najib, Bouhaddi, Noureddine, Guedri, Mohamed

Publikováno v: International Modal Analysis Conference
International Modal Analysis Conference, Feb 2015, Orlando, FL, United States

International audience; Among probabilistic uncertainty propagation methods, the generalized Polynomial Chaos Expansion (gPCE) has recently shown a growing emphasis. The numerical cost of the non-intrusive regression method used to compute the gPCE c
