A non-intrusive method to get a multi-element polynomial chaos model is developed. This method is called ME-ACD, for Multi-Element based on Agglomerative Clustering on Derivatives. It aims at approximating a Quantity of Interest which presents discon

This thesis introduces two methods dedicated to the stochastic modeling of bladed disk in linear and nonlinear contexts. The current challenge for aircraft engine designers is to predict, at low cost, the vibration behavior of bladed disks according

In order to ensure the integrity of rotating machines, it is necessary to predict the critical speeds and associated vibration amplitudes. The design of such structures requires considering the variability of a large number of parameters of different

Slender structural systems, susceptible to unstable bifurcation, generally lose stability at lower load levels than the linear buckling load of the perfect structure. In the present work, the different dynamic balance configurations in nonlinear osci

The use of passive nonlinear absorbers called Nonlinear Energy Sink (NES) has proven its effectiveness as an alternative solution for passive vibration control by combining the advantages of the earlier technologies. However, the dynamic behaviour of
