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.

About the author
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).
