Journal Article
Muguda, S., Hughes, P., Augarde, C., Perlot, C., Bruno, A., & Gallipoli, D. (2022). Cross-linking of biopolymers for stabilising earthen construction materials. Building Research and Information, 50(5), 502-514. https://doi.org/10.1080/09613218.2021.2001304

Biopolymers are promising potential soil stabilizers due to their ease of application and stabilization efficacy. Biopolymers are biologically occurring polymers that form hydrogels when added to soil in the presence of water. Hydrogels are three-dim...

A Displacement-controlled Arc-Length Solution Scheme (2021)
Journal Article
Pretti, G., Coombs, W., & Augarde, C. (2022). A Displacement-controlled Arc-Length Solution Scheme. Computers and Structures, 258, Article 106674. https://doi.org/10.1016/j.compstruc.2021.106674

Tracing load-displacement paths in structural mechanics problems is complicated in the presence of critical points of instability where conventional load- or displacement control fails. To deal with this, arc-length methods have been developed since... Read More about A Displacement-controlled Arc-Length Solution Scheme.

Point collocation methods are strong form approaches that can be applied to continuum mechanics problems and possess attractive features over weak form-based methods due to the absence of a mesh. While various adaptive strategies have been proposed t... Read More about An adaptive local maximum entropy point collocation method for linear elasticity  .
