Full-Field Strain and Stress Reconstruction Using a Hybrid ML–iFEM Approach

e-Journal of Nondestructive Testing
Accurate full-field reconstruction of structural stress and strain remains a central challenge in structural health monitoring, particularly when only sparse sensing data are available during operation. While the inverse finite element method (iFEM) is widely recognised for its robustness in displacement and stress estimation, its practical ...

Shape Sensing of a Complex Aeronautical Structure with Inverse Finite Element Method

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,
