Shakedown analysis of incompressible materials under cyclic loads: A locking-free CS-FEM-Q5 numerical approach

PLH Ho, C Lee, CV Le, JJ Yee - International Journal of Non-Linear …, 2024 - Elsevier
Volumetric locking may occur in plastic analysis of incompressible materials using low-order
finite elements due to incompressibility constraints. This study presents a locking-free …

Dual failure analysis of 3D structures under cyclic loads using bFS-FEM based numerical approaches

PLH Ho, CV Le, C Lee, DT Tran, PH Nguyen… - Finite Elements in …, 2024 - Elsevier
Failure mechanism of 3D structures cannot always be produced by the low-order finite
elements due to the so-called volumetric locking effect. In this paper, dual numerical …

Adaptive quadtree edge-based smoothed finite element method for limit state analysis of structures

PLH Ho, C Lee - International Journal of Mechanics and Materials in …, 2024 - Springer
This study presents an efficient numerical approach for pseudo-lower bound limit analysis of
structures. The total stress field is decomposed into two components: an elastic component …
