Towards Automatic Crack Size Estimation with iFEM for Structural Health Monitoring [PDF]

open access: yesSensors, 2023
The inverse finite element method (iFEM) is a model-based technique to compute the displacement (and then the strain) field of a structure from strain measurements and a geometrical discretization of the same. Different literature works exploit the error
