Real-Time monitoring of crack propagation in fiber-reinforced composite plates using iFEM methodology

, 2021
Inverse finite element method (iFEM) is an efficient and robust approach to obtain displace- ment/strain/stress state of the structure by monitoring strain values obtained from discrete locations in the structure. Therefore, the iFEM methodology can precisely detect any variation in strain field of the structure due to presence of damages inside the ...

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

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”.

Least‐Squares Projected Models for Non‐Intrusive Affinization of Reduced Basis Methods

International Journal for Numerical Methods in Engineering, Volume 126, Issue 18, 30 September 2025.
ABSTRACT Reduced‐basis methods (RBMs) constitute a promising technique for delivering numerical solutions of parameterized PDEs in real time and with reasonable accuracy. The most significant drawback of RBMs is the requirement of parametric affinity, a condition that only very trivial problems satisfy.

Optimal Sensor Placement for Inverse Finite Element Reconstruction of Three-Dimensional Frame Deformation

International Journal of Aerospace Engineering, 2018
The inverse finite element method (iFEM) for the 3D framework deformation reconstruction was introduced. As the process of iFEM did not require a priori knowledge, such as the modal shape, the loading, and the elastic-inertial material information of the
