Numerical analysis of anisotropic stiffness and strength for geomaterials

Autor: Fei Song, Manuel A. González-Fernández, Alfonso Rodriguez-Dono, Leandro R. Alejano

Publikováno v: Journal of Rock Mechanics and Geotechnical Engineering, Vol 15, Iss 2, Pp 323-338 (2023)

In numerical modelling, selection of the constitutive model is a critical factor in predicting the actual response of a geomaterial. The use of oversimplified or inadequate models may not be sufficient to reproduce the actual geomaterial behaviour. T

Modelling underground excavations in rock masses with anisotropic time-dependent behaviour

Autor: Fei Song, Alfonso Rodriguez-Dono, Patricio Sanchez Farfan

When modelling rock masses that behave anisotropically and in addition present a time dependent behaviour, it is relevant to select a constitutive model able to represent their actual behaviour realistically. This article presents an alternative anis

A new approach to model geomaterials with heterogeneous properties in thermo-hydro-mechanical coupled problems

Autor: Alfonso Rodriguez-Dono, Yunfeng Zhou, Sebastia Olivella

Publikováno v: Computers and Geotechnics. 159:105400

The main objective of this article is to present a new approach to model coupled thermo-hydro-mechanical problems considering geomaterials with heterogeneous properties. This approach has been implemented in the software CODE_BRIGHT and it provides t
