iFEM benchmark problems for solid elements

Smart Materials and Structures, 2019
Abstract Structural health monitoring (SHM) is a growing field of research, as it has the potential to simultaneously improve the reliability of structures and reduce their maintenance cost. SHM requires accurate stress and strain information, preferably for the entire structure.

Integrated Free Energy Model (IFEM) for microemulsions

Journal of Colloid and Interface Science, 2016
The Integrated Free Energy Model (IFEM) is a platform used to predict the solubilization of nonpolar oils in nonionic alkyl-polyethylene oxide (C(X)EO(Y)) micelles starting from a free energy balance of costs and gains when surfactants from empty micelles and oil from a continuous oil phase assemble to form an oil-swollen micelle.

Experimental shape sensing of a wing structure using SSB-iFEM: Static assessment and dynamic wind tunnel test [PDF]

Measurement: Journal of the International Measurement Confederation
Reconstructing the displacement field from discrete strain measurements, commonly known as shape sensing, plays a crucial role in the development of advanced Structural Health Monitoring (SHM) frameworks. Monitoring displacements throughout a structure’s

IFEMS: a new approach for monitoring wildfire evolution with NOAA-AVHRR imagery

International Journal of Remote Sensing, 2001
A new approach for monitoring wildfire evolution was developed. It was achieved by integrating both the burned area mapping system and the fire detection system. Multi-spectral multi-temporal images of the National Oceanic and Atmospheric Administration Advanced Very High Resolution Radiometer (NOAA-AVHRR) were employed. The new system has an excellent

On a staggered iFEM approach to account for friction in compression testing of soft materials

Journal of the Mechanical Behavior of Biomedical Materials, 2013
An inverse finite element method (iFEM) to estimate material parameters from compression tests of soft materials is presented, where alginate hydrogel was used as a phantom material. The method applies if the boundary conditions at the loaded surfaces are not ideal, i.e.

Multi-Plate Joint Modelling for GFEM and IFEM

Volume 5: Structures, Structural Dynamics & Materials
Abstract Present day engineering, especially that of modern airplane structures, requires that we join several structural components using fasteners to serve the engineered purpose. Design and analysis of such fastener joints become challenging with increase in number of stacking plates.

Updated Shape Monitoring of Morphing Wing Structures Using iFEM and SSB-iFEM: Applications to Composite and Modular Architectures

Aircraft wings are traditionally designed as compromise configurations, able to provide acceptable performance over a range of flight conditions without being optimal at each operating point. Morphing-wing technologies, and trailing-edge morphing concepts in particular, can reduce this compromise by enabling continuous adaptation of the aerodynamic ...

IFEM method for distributed monitoring of cable forces in cable-stayed bridges

Structural Health Monitoring
The method proposed in this article pertains to developing a technique for structural health monitoring of cable-stayed bridges based on the inverse finite element method (iFEM). This approach is built on distributed monitoring of strains by using a Brillouin scattering-based distributed optical fiber sensor. Using this method, both the deflections and

Improving iFEM-based wing deformation reconstruction accuracy with IMU-assisted calibration

Measurement Science and Technology
Abstract To address the degradation in reconstruction accuracy of inverse finite element methods (iFEMs) for wing deformation—caused by discrepancies between the simulation model and the physical system, including model simplifications, mismatched loading conditions, and strain sensor installation errors—as well as the high cost and ...
