A localization and updating strategy of large finite element models in structural dynamics

In this paper, a subspace fitting method is proposed to update, in the time domain, the finite element model of a rotating machine.. The procedure is achieved by minimizing an

This methodology allows (1) to analyse the propagation of these uncertainties into the dynamical response of the structure, (2) to take into account these uncertainties in the

It can also be seen that the updated uncertain computational model related to the eigenvector probabilistic constraint is more sensitive to the updated mean parameter s opt than to

The same approach is used for Moiré hole drilling analysis: the inverse or backward problem requires the observed displacement fields and knowledge of the elastic material prop-

We introduce here a new method to obtain the Taylor series expansion of the objective function, called the Finite Element Method over a Polynomial Algebra (FEMPA), that keeps

Twenty-seven parameters dealing with failure criteria, model construction, material laws, boundary conditions, and model validation were extracted from the included articles.. From

The part (a) of these figures demonstrates the mean value of the predicted parameters and part (b) is the Coefficient of Variation of the estimated parameters. Figures 3, 4 and

In this work, the starting point is that there will be two models for each machine tool configuration: numerical (finite element) and experimental, which
