Résumé :

This text covers recent progress in several key areas, such as air-water-soil mixture, cyclic constitutive models, anisotropic models, noncoaxial models, gradient models, compaction bands, and the instability of unsaturated soils. It also includes computational modeling to large-scale excavation of ground and methane hydrate development.

Biographie:

Fusao Oka is a professor emeritus of Kyoto University and president of the

LIQCA Liquefaction Geo Research Institute. Until 1997, he was a professor

in the Department of Civil and Earth Resources Engineering of Kyoto

University. He specializes in computational geomechanics with particular

regard to constitutive equations, consolidation, liquefaction, and strain

localization analyses. He organized several international conferences and

workshops, such as the Fourth International Workshop on Localization and

Bifurcation Theory for Soils and Rocks (1997), the ISSMGE International

Symposium on Deformation and Progressive Failure in Geomaterials (1997),

the International Symposium on Prediction and Simulation Methods for

Geohazard Mitigation (2009), and the 14th International Conference of

IACMAG (2014). He has published more than 300 papers on geomechanics

and is a co-author of Computational Modeling of Multiphase Geomaterials

(CRC Press, 2012).

Sayuri Kimoto had been working on geomechanics as an associate professor

at Kyoto University for years. She is presently a professor of Osaka Sangyo

University. She specializes in the elasto-viscoplastic constitutive equations

of soils and the numerical analysis of multiphase geomaterials, such as the

behavior analysis of seabed ground due to the production of methane gas.

She is a co-author of Computational Modeling of Multiphase Geomaterials

(CRC Press, 2012).
