Shape Sensing of a Complex Aeronautical Structure with Inverse Finite Element Method [PDF]
Sensors, 2021 The inverse Finite Element Method (iFEM) is receiving more attention for shape sensing due to its independence from the material properties and the external load. However, a proper definition of the model geometry with its boundary conditions is required,

Finite element method-enhanced neural network for forward and inverse problems
Advanced Modeling and Simulation in Engineering Sciences, 2023 We introduce a novel hybrid methodology that combines classical finite element methods (FEM) with neural networks to create a well-performing and generalizable surrogate model for forward and inverse problems. The residual from finite element methods and

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).
