Damage Localisation in Thin Plates Using the Inverse Finite Element Method
2019This work investigates the use of the inverse Finite Element Method (iFEM) for damage localisation by reconstructing the damaged strain field of the structure. The iFEM is a proven technique for reconstructing the displacement field of a structure using surface strain measurements from discrete locations on the structure.

Automated procedure for InSAR data inversion using Finite Element Method
2008 Second Workshop on Use of Remote Sensing Techniques for Monitoring Volcanoes and Seismogenic Areas, 2008Source inversions performed using different kind of static deformation data, such as GPS displacements, DInSAR imagery, levelling and EDM measurements, suggest that slip on fault is usually not uniform and is better modeled as a distribution of dislocation sources. To this aim, we developed an automated procedure for geodetic data inversion to estimate

2D Laplace‐domain waveform inversion using adaptive finite element method
SEG Technical Program Expanded Abstracts 2009, 2009Summary Waveform inversion in the Laplace domain has been proposed recently. The Laplace-domain waveform inversion is robust, is not sensitive to the initial model, and generates a long-wavelength velocity model for field data as it exploits a well behaved objective function.

Cross-borehole inverse scattering using a boundary finite-element method
Inverse Problems, 1998Summary: The problem of the reconstruction of the shape of a perfectly conducting cylinder in a cross-borehole configuration is addressed. The initial data is the harmonic electromagnetic field diffracted by the object to a receiving borehole. The method is based on an iterative conjugate gradient algorithm which requires the solving of two reciprocal ...

Shape sensing with inverse Finite Element Method for slender structures
2019The methodology known as "shape sensing" allows the reconstruction of the displacement field of a structure starting from strain measurements, with considerable implications for structural monitoring, as well as for the control and implementation of smart structures. An approach to shape sensing is based on the inverse Finite Element Method (iFEM) that

A Modified Inverse Eigensensitivity Method for Large Finite Element Models
Finite element models should represent the dynamic behavior of real structures accurately to be subsequently used in design purposes. Therefore, finite element model updating methods have been developed in order to decrease the difference between analytical model and modal test results.Dogu§ Unlu +2 more

Inverse and Feedback Analyses Based on the Finite Element Method
2018To undertake a successful computation task concerning the construction and operation process of hydraulic structures, one of the mostly concerned obstacles is the limited or incomplete sets of input data. This chapter presents the study on the inverse and feedback analyses for hydraulic structures using the FEM, intended to provide another parametric ...
