Conforming and nonconforming finite element methods for biharmonic inverse source problem [PDF]
Inverse Problems, 2021 Abstract This paper deals with the numerical approximation of the biharmonic inverse source problem in an abstract setting in which the measurement data is finite-dimensional. This unified framework in particular covers the conforming and nonconforming finite element methods (FEMs).

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,

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 ...
