State-of-the-art review on the use of AI-enhanced computational mechanics in geotechnical engineering
Significant uncertainties can be found in the modelling of geotechnical materials. This can
be attributed to the complex behaviour of soils and rocks amidst construction processes …

A phase‐field approach for compaction band formation due to grain crushing
Compaction bands are tabular regions of localized compressive deformation with little or no
shear offset. Often observed in high‐porosity rocks, they can be classified into several …

Evolution of anisotropy with saturation and its implications for the elastoplastic responses of clay rocks
Many clay rocks have distinct bedding planes. Experimental studies have shown that their
mechanical properties evolve with the degree of saturation (DOS), often with higher stiffness …
