An investigation into the methods for modelling pre-existing cracks in phase field problems (2023)
Presentation / Conference Contribution
Sims, B., Bird, R., Giani, S., & Coombs, W. (2023, April). An investigation into the methods for modelling pre-existing cracks in phase field problems. Presented at UKACM 2023, Warwick, UK

Phase field (PF) models are an increasingly popular method of numerically modelling fracture problems. While research has focused on the practical applications and computational efficiency of PF methods, little discussion exists around the merits of...

A ghost-stabilised material point method for large deformation geotechnical analysis (2023)
Presentation / Conference Contribution
Coombs, W. (2023, June). A ghost-stabilised material point method for large deformation geotechnical analysis. Presented at 10th European Conference on Numerical Methods in Geotechnical Engineering, London

The Material Point Method (MPM) is advertised as the method for large deformation analysis of geotechnical problems. However, the method suffers from several instabilities which are widely documented in the literature, such as: material points crossi...

Techno-Economic-Environmental Analysis for Net-Zero Sustainable Residential Buildings (2023)
Presentation / Conference Contribution
Garg, A., Aujla, G., & Sun, H. (2023, October). Techno-Economic-Environmental Analysis for Net-Zero Sustainable Residential Buildings. Presented at IEEE PES ISGT Europe 2023, Grenoble, France

Carbon emissions are becoming a global concern responsible for climate change. The renewable energy sources (RESs) such as wind, solar, biomass are gaining importance to reduce emissions in the energy sector. However, these sources depend highly on v...

Cone Penetration Tests (CPTs) in layered soils: a Material Point approach (2023)
Presentation / Conference Contribution
Bird, R., Coombs, W., Augarde, C., Brown, M., Sharif, Y., Carter, G., Johnson, K., & Macdonald, C. (2023, June). Cone Penetration Tests (CPTs) in layered soils: a Material Point approach. Presented at 10th European Conference on Numerical Methods in Geotechnical Engineering, London

Cone Penetration Tests (CPTs) can be used to determine in-situ soil properties and represent a practical choice for site investigation offshore, especially for linear infrastructure, such as offshore wind export cables. Information gained from CPTs i... Read More about Cone Penetration Tests (CPTs) in layered soils: a Material Point approach.

On the development of a material point method compatible arc length solver for large deformation solid mechanics (2023)
Presentation / Conference Contribution
Gavin, N., Coombs, W., Brigham, J., & Augarde, C. (2023, April). On the development of a material point method compatible arc length solver for large deformation solid mechanics. Presented at UKACM 2023, Coventry, UK

The Material Point Method is a versatile technique, however, it may be unable to provide a valid solution if there is a snap-through or snap-back response in the equilibrium path. One approach of overcoming this issue is the use of path following tec...
