Web crippling strength of cold-formed steel lipped channels under interior-two-flange loading
This study presents a novel application of explainable machine learning techniques to investigate the web crippling behaviour of Cold-Formed Steel (CFS) lipped channel beams under Interior-Two-Flange

Materials Today Communications
Machine learning has been used to model the moment-rotation behaviour of steel extended endplate connections based on geometric parameters. However, these black-box models lack interpretability. This

Journal of Composite Structures (Q1) – Undergraduate research
Carbon fibre woven composites have emerged as engineered materials for lightweight, tailorable and high-performance applications. Predicting their macroscale mechanical properties remains a challenge due to uncertainties
