Towards Automatic Crack Size Estimation with iFEM for Structural Health Monitoring

Sensors, 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

A smoothed iFEM approach for efficient shape-sensing applications: Numerical and experimental validation on composite structures [PDF]

Mechanical Systems and Signal Processing, 2021
Abstract A smoothed inverse finite element method (iFEM(s)) is developed by coupling the inverse finite element method (iFEM) and the smoothing element analysis (SEA) for real-time reconstruction of displacement field utilizing a network of discrete strain-sensor measurements. This reconstruction is commonly referred to as “shape sensing”.

Shape Sensing of Beam-Like Structures Using the Robust iFEM-iQS4 Inverse Shell Element

IEEE Transactions on Instrumentation and Measurement, 2023
The reconstruction of 2-D/3-D deformation and stress fields using a limited number of strain sensors is called "shape sensing" and it plays an important role in structural health monitoring (SHM) methods. The inverse finite element method (iFEM) is one of the best shape sensing algorithms developed based on strain data from a set of on-board/embedded ...

Structural health monitoring of an offshore wind turbine tower using iFEM methodology [PDF]

Ocean Engineering, 2020
With the increasing popularity of wind energy, offshore wind turbines (OWTs) are currently experiencing rapid development. The tower is one of the most significant components of the OWT. However, the tower will not only stand its own weight and weight of the top structure, but also be surrounded by harsh wave and wind loading conditions.
