A discrete element modelling of bonded granulates and investigation on the bond effect on
their behaviour are very important to geomechanics. This paper presents a two‐dimensional …

This paper extends the hierarchical multiscale approach developed earlier by the authors to
model the coupled hydro-mechanical behaviour for saturated granular soils. Based on a …

Computational Modeling of Multiphase Geomaterials discusses how numerical methods
play a very important role in geotechnical engineering and in the related activity of …

This paper presents a numerical investigation on the strain localization of an idealized sand
in biaxial compression tests using the distinct element method (DEM). In addition to the …

This is a review of the papers written by the author with co-researchers, which have been
published in Soils & Foundations and related publications. The contents of the papers are …

Since strain localization is a precursor of failure, it is an important subject to address in the
field of geomechanics. Strain localization has been analysed for geomaterials by several …

In order to investigate the formation of the shear band in methane hydrate-bearing
sediments (MHBS), an elasto-plastic constitutive model was proposed and implemented into …

Strain localization is an important geotechnical problem related to large deformations and
the onset of failure, such as slope failure. It is necessary, therefore, to clarify the mechanisms …

Studies on constitutive modeling and numerical analysis methods have been well
developed. Nowadays, numerical and analytical methods play a very important role in …

A linear instability analysis was performed in order to investigate which variables have a
significant effect on the onset of the instability of an unsaturated viscoplastic material …
