Structural model updating and prediction variability using Pareto optimal models [PDF]
, 2008 A multi-objective identification method for structural model updating based on modal residuals is presented. The method results in multiple Pareto optimal structural models that are consistent with the experimentally measured modal data and the modal ...

Finite element model updating for damage detection [PDF]
PAMM, 2005 AbstractIn this contribution we derive the iterative finite element model updating algorithm. The ability of the method to detect the damage is verified by means of a simulation with a reference finite element model. (© 2005 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

Updating of Finite Element Models Including Damping [PDF]
Transactions of the Korean Society for Noise and Vibration Engineering, 2012 Finite element models are updated in two stages in this paper. In the first stage, damping is neglected, and mass and stiffness matrices of a finite element model are updated using an optimization technique. The objective function for optimization consists of natural frequencies and mode shapes obtained from experimental modal testing data and finite ...

Finite element model updating of natural fibre reinforced composite structure in structural dynamics
MATEC Web of Conferences, 2016 Model updating is a process of making adjustment of certain parameters of finite element model in order to reduce discrepancy between analytical predictions of finite element (FE) and experimental results.

Three Case Studies in Finite Element Model Updating
Shock and Vibration, 1995 This article summarizes the basic formulation of two well-established finite element model (FEM) updating techniques for improved dynamic analysis, namely the response function method (RFM) and the inverse eigensensitivity method (IESM).

Finite element analysis of natural fiber composites using a self-updating model [PDF]
, 2020 The aim of the current work was to illustrate the effect of the fibre area correction factor on the results of modelling natural fibre-reinforced composites. A mesoscopic approach is adopted to represent the stochastic heterogeneity of the composite, i.e.
