A fully coupled computational framework for fluid pressurised crack evolution in porous media (2019)
Journal Article
Hardcastle, A., Mousavi Nezhad, M., Rezania, M., Tizani, W., & Gamage Ranjith, P. (2019). A fully coupled computational framework for fluid pressurised crack evolution in porous media. Journal of Porous Media, 22(8), 939-956. doi:10.1615/jpormedia.2019025665

This paper presents a computational framework for modelling hydraulic fracture on the basis of combining continuum porous media and damage theories. By considering the continuum as two separate domains of damaged and intact porous domains, model comp... Read More

The current study investigates the short rotation coppice (SRC) gasification in a bubbling fluidized bed gasifier (BFBG) with air as gasifying medium. The thermochemical processes during combustion were studied to get better control over the air gasi... Read More

Nonlinear soil-pile interaction induced by ground settlements: pile displacements and internal forces (2019)
Journal Article
Franza, A., Marshall, A., & Jimenez, R. (in press). Nonlinear soil-pile interaction induced by ground settlements: pile displacements and internal forces. Géotechnique,

In urban areas, the construction of tunnels and deep-excavations beneath and near to pile foundations can be detrimental for the superstructure and the foundation. A two-stage continuum-based nonlinear soil-pile interaction model is presented in this... Read More

Comparison of two noise reduction methods in coherence scanning interferometry for surface measurement (2019)
Conference Proceeding
Gomez, C., Su, R., Lawes, S., & Leach, R. (2019). Comparison of two noise reduction methods in coherence scanning interferometry for surface measurement

Coherence scanning interferometry (CSI) can measure relatively flat surfaces with sub-nanometre precision, but the measurement noise may increase significantly if the intensity of the interferometric signal reduces when measuring non-flat surfaces or... Read More

Does interferometry work? A critical look at the foundations of interferometric surface topography measurement (2019)
Journal Article
de Groot, P. J., Colonna de Lega, X., Su, R., & Leach, R. K. (2019). Does interferometry work? A critical look at the foundations of interferometric surface topography measurement. Proceedings of SPIE, 11102, https://doi.org/10.1117/12.2526654

Interferometers for the measurement of surface form and texture have a reputation for high performance. However, the results for many types of surface features can deviate from the expectation of one cycle of phase shift per half wavelength of surfac... Read More
