Sequential surrogate modeling for efficient finite element model updating

Computers & Structures, 2016
This study propose a sequential surrogate modeling for FE model updating.Identical input parameters can produce simple and highly complex response-surfaces.Accordingly, the use of the identical samples for surrogate modeling is not efficient.The proposed method adds samples automatically based on the Kriging model.The proposed method can be customized ...

Link relation updating of finite element model

International Journal of Applied Electromagnetics and Mechanics
“ Tie” constraint is commonly used to establish the link relation of structural finite element model (FEM) in engineering. In this paper, the constrained area is taken as the updated object, and modal test data is used to update the structural FEM.

Finite Element Model Updating of a Steel Jacket Scale Model

Applied Mechanics and Materials, 2012
In this paper, the finite element model of a steel jacket scale model is updated using modal parameters identified by modal test. Updating parameters are selected based on sensitivity analysis by solving modal energies. And then, a two-steps updating process is carried out using different parameters and the Cross-Model Cross-Mode (CMCM) model updating ...

Inherently incomplete finite element model and its effects on model updating

AIAA Journal, 2000
Some of the questions regarding the use of measured data to improve a e nite element model of a structure to makeit betterableto predict the dynamicbehaviorof thestructureare addressed. Theissues discussed includethe following: All such models are truly reduced models, the parameters of a reduced model of a linear structure vary with frequency, a ...

Finite Element Model Updating Using the Local Correspondence Principle

2018
In this, paper an overview of a Finite Element (FE) model updating technique based on the Local Correspondence (LC) principle is presented. The main idea behind the LC technique is to update the FE model by replacing the mode shape vectors and natural frequencies with their corresponding experimental counterparts obtained from an output-only modal ...
