An Analysis of Finite Element Approximation in Electrical Impedance Tomography [PDF]

open access: yes, 2013
We present a finite element analysis of electrical impedance tomography for reconstructing the conductivity distribution from electrode voltage measurements by means of Tikhonov regularization. Two popular choices of the penalty term, i.e., $H^1(\Omega)$-

Swarm Intelligent Optimization Conjunction with Kriging Model for Bridge Structure Finite Element Model Updating

open access: yesBuildings, 2022
For the simple bridge structure, the finite element model established by drawing and elastic mechanics method is accurate. However, when faced with large and complex long-span bridge structures, there are inevitable differences between the finite element

Finite Element Model Updating Using FRF Measurements

open access: yesShock and Vibration, 2005
This study presents a new updating method based on measured frequency response functions. The objective function of the minimization procedure is formed by the difference between the measured and the analytical frequency responses.
