Two-Step Calibration Method for Inverse Finite Element with Small Sample Features
Sensors, 2020 When the inverse finite element method (inverse FEM) is used to reconstruct the deformation field of a multi-element structure with strain measurements, strain measurement errors can lower the reconstruction accuracy of the deformation field. Furthermore,

Sensors, 2023 The inverse finite element method (iFEM) is a novel method for reconstructing the full-field displacement of structures by discrete measurement strain. In practical engineering applications, the accuracy of iFEM is reduced due to the positional offset of

An Introduction to Finite Element Methods for Inverse Coefficient Problems in Elliptic PDEs [PDF]
Jahresbericht der Deutschen Mathematiker-Vereinigung, 2021 AbstractSeveral novel imaging and non-destructive testing technologies are based on reconstructing the spatially dependent coefficient in an elliptic partial differential equation from measurements of its solution(s). In practical applications, the unknown coefficient is often assumed to be piecewise constant on a given pixel partition (corresponding ...

Inverse finite element method for large‐displacement beams
International Journal for Numerical Methods in Engineering, 2010 AbstractA finite element model for the inverse analysis of large‐displacement beams in the elastic range is presented. The model permits determining the initial shape of a beam such that it attains the given design shape under the effect of service loads.

IMPACT OF MATRIX INVERSION ON THE COMPLEXITY OF THE FINITE ELEMENT METHOD
Science and Transport Progress, 2016 Purpose. The development of a wide construction market and a desire to design innovative architectural building constructions has resulted in the need to create complex numerical models of objects having increasingly higher computational complexity. The purpose of this work is to show that choosing a proper method for solving the set of equations can ...

Application of Bilinear Softening Laws and Fracture Toughness of Foamed Concrete
Construction Materials, 2023 This study examined the fracture and failed performance of foamed concrete materials by testing normalized notched beams under three-point bending via three methods: inverse analysis, digital image correlation (DIC), and finite element modeling (FEM). It

The inverse deformation mapping in the finite element method
Philosophical Magazine, 2005 This paper aims at the exploitation of material forces to find an optimum mesh in the finite element method (FEM). The classical variational formulation provides the linear momentum equation in a Lagrangian description. A variational setting for the derivation of the canonical momentum equation in the Eulerian description is presented.
