Shape Sensing of Plate and Shell Structures Undergoing Large Displacements Using the Inverse Finite Element Method

Shock and Vibration, 2018
The inverse Finite Element Method (iFEM) is applied to reconstruct the displacement field of a shell structure which undergoes large deformations using discreet strain measurements as the prescribed data.

Using the inverse finite‐element method to harmonise classical modal analysis with fibre‐optic strain data for robust population‐based structural health monitoring

Strain, Volume 61, Issue 1, February 2025.
Abstract Vibration‐based approaches to structural health monitoring (SHM) gained increasing significance for assessing the behaviour of existing structures because of their non‐intrusive nature and high sensitivity to damage. However, data availability often limits the application of SHM approaches.

Structural health monitoring of precracked structures using an in‐plane inverse crack‐tip element

International Journal of Mechanical System Dynamics, Volume 4, Issue 4, Page 406-426, December 2024.
Abstract This study investigates the application of the inverse finite element method (iFEM) in fracture mechanics by developing a novel two‐dimensional six‐node triangular inverse crack‐tip element. With its simplified formulation, the proposed inverse element is computationally efficient and ensures strain singularity at the crack tip by ...

A multiscale preconditioner for crack evolution in porous microstructures: Accelerating phase‐field methods

International Journal for Numerical Methods in Engineering, Volume 125, Issue 11, 15 June 2024.
Abstract Phase‐field methods are attractive for simulating the mechanical failure of geometrically complex porous microstructures described by 2D/3D x‐ray μ$$ \mu $$CT images in subsurface (e.g., CO 2$$ {}_2 $$ storage) and manufacturing (e.g., Li‐ion battery) applications.
