TL;DR: In this article, a dynamic test bed based on a bolted structure is designed and modal testing is performed for the purpose of improving our understanding and the development of pertinent models, and the results of the experimental campaign show the variation of the dissipation in a bolted joint and its apparent stiffness as a function of joint conditions.

TL;DR: A general framework that enables to perform real-time validation of mechanical models based on the constitutive relation error and a powerful method for model reduction, the proper generalized decomposition is introduced.

TL;DR: In this paper, a linear joint model is proposed to represent the behavior of every joint of a large aeronautical structure globally while enabling local nonlinear reanalysis of the most highly loaded joints.

TL;DR: This model is based on the calculation and the minimization of Rayleigh's quotient and uses an energetic approach from beam theory applied to stators with a Timoshenko kinematic model to determine mechanical eigenfrequencies.

TL;DR: In this article, the authors present a review of the main probabilistic approaches used to model and propagate uncertainties in structural mechanics and present the Lack-Of-Knowledge theory that was recently developed to take into account all sources of uncertainties.
