Multigrid Methods for Hellan-Herrmann-Johnson Mixed Method of Kirchhoff Plate Bending Problems
, 2017 A V-cycle multigrid method for the Hellan-Herrmann-Johnson (HHJ) discretization of the Kirchhoff plate bending problems is developed in this paper. It is shown that the contraction number of the V-cycle multigrid HHJ mixed method is bounded away from one

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

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

Shape sensing with iFEM on a type IV pressure vessel based on experimental measurements
e-Journal of Nondestructive TestingThe service life of a ship depends on its structural integrity, which can be undermined through time via different loading conditions. The incorporation of a Structural Health Monitoring (SHM) system could enhance the safety of the vessel because ...
