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

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., $H^1(\Omega)$-

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.

Finite Element Modeling of Drillstrings [PDF]

open access: yesMathematical and Computational Applications, 1996
A finite element model is presented for investigating dynamic behavior of drillstrings used in oil and gas wells. A Timoshenko beam element is used to model axial and transverse vibrations. The effect of axial load, gravity, the constraints due to stabilizers are considered.
