Localisation in computational geomechanics: a nonlinear micropolar approach (2025)
Thesis
O'Hare, T. (2025). Localisation in computational geomechanics: a nonlinear micropolar approach. (Thesis). Durham University. https://durham-repository.worktribe.com/output/4127813

The localisation of strain into narrow bands of intense deformations is a pervasive phenomenon in geomechanics. It is closely associated with catastrophic failure - landslides, slope collapses, rock faulting, etc. - and has significant implications f...

Simulation of strain localisation with an elastoplastic micropolar material point method (2024)
Presentation / Conference Contribution
O'Hare, T. J., Gourgiotis, P. A., Coombs, W. M., & Augarde, C. E. (2024, April). Simulation of strain localisation with an elastoplastic micropolar material point method. Presented at 2024 UK Association for Computational Mechanics Conference, Durham, UK

The thickness of shear bands, which form along slip surfaces during certain modes of geotechnical failure, depends directly on the size of the soil particles. Classical continuum models, however, are invariant to length scale, so the strain localisat...

An implicit Material Point Method for micropolar solids undergoing large deformations (2023)
Journal Article
O'Hare, T., Gourgiotis, P., Coombs, W., & Augarde, C. (2024). An implicit Material Point Method for micropolar solids undergoing large deformations. Computer Methods in Applied Mechanics and Engineering, 419, Article 116668. https://doi.org/10.1016/j.cma.2023.116668

Modelling the mechanical behaviour of structural systems where the system size approaches that of the material microstructure (such as in MEMS) presents challenges to the standard continuum assumption and classical models can fail to predict importan...

A geometrically-exact Finite Element Method for micropolar continua with finite deformations (2023)
Presentation / Conference Contribution
O'Hare, T. J., Gourgiotis, P. A., Coombs, W. M., & Augarde, C. E. (2023, April). A geometrically-exact Finite Element Method for micropolar continua with finite deformations. Paper presented at UKACM 2023, University of Warwick, Coventry, UK

Micropolar theory is a weakly non-local higher-order continuum theory based on the inclusion of independent (micro-)rotational degrees of freedom. Subsequent introduction of couple-stresses and an internal length scale mean the micropolar continuum i...

The Virtual Element Method for Engineers (2022)
Presentation / Conference Contribution
O'Hare, T., & Augarde, C. (2022, April). The Virtual Element Method for Engineers. Paper presented at UKACM 2022, Nottingham, England

The virtual element method (VEM) is a relatively new technique, similar to the finite element method (FEM), but having no restriction on the number of element sides. This has numerous advantages, particularly regarding greater meshing flexibility, ho... Read More about The Virtual Element Method for Engineers.
