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

open access: yesInternational 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 ...

Comparative muscle anatomy of the anuran pelvis and hindlimb in relation to locomotor mode

open access: yesJournal of Anatomy, Volume 245, Issue 5, Page 751-774, November 2024.
Scientists at UCL and the Royal Veterinary College have digitally dissected the musculoskeletal anatomy of the pelvis and hindlimbs of 30 frog species using contrast‐enhanced microCT scanning, forming the largest digital anatomical dataset in any vertebrate group to date.

Inverse Finite Element Method for Reconstruction of Deformation in the Gantry Structure of Heavy-Duty Machine Tool Using FBG Sensors

open access: yesSensors, 2018
The deformation of the gantry structure in heavy-duty machine tools is an important factor that affects machining accuracy. In order to realize real-time monitoring of the deformation of the gantry structure, which is statically indeterminate and complex

Finite element analysis with deformed shape constraints generated by laser‐scanned point clouds

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 125, Issue 19, 15 October 2024.
Abstract This article proposes a computational method for finite element analysis with deformed shape constraints for analyzing constructed structures to account for deformations that occur before shape measurement by a terrestrial laser scanner (TLS).

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

open access: yesInternational 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.

A theoretical and numerical investigation of a family of immersed finite element methods [PDF]

open access: yes, 2019
In this article we consider the widely used immersed finite element method (IFEM), in both explicit and implicit form, and its relationship to our more recent one-field fictitious domain method (FDM). We review and extend the formulation of these methods,

Improved FEM for distribution network cables rating using multiple forgetting factors least-square

open access: yesAIP Advances, 2018
Complicated surroundings of distribution network cables make it difficult to compute maximum ampacity according to actual operations. However, single numerical method for cable rating causes complex computation load which is not suitable for ampacity ...

Influence of soil plasticity models on offshore wind turbine response

open access: yesWind Energy, Volume 27, Issue 2, Page 131-151, February 2024.
Abstract While recent numerical modelling advances have enabled robust simulation of foundation hysteresis behaviour, uptake of these models has been limited in the offshore wind industry. This is partially due to modelling complexity and the unknown influence of including such soil constitutive models within a design philosophy.
