Numerical methods are very powerful tools for use in geotechnical engineering, particularly in computational geotechnics. Interest is strong in the new field of multi-phase nature of geomaterials, and the area of computational geotechnics is expanding.
Alongside their companion volume Computational Modeling of Multiphase Geomaterials (CRC Press, 2012), Fusao Oka and Sayuri Kimoto cover recent progress in several key areas, such as air-water-soil mixture, cyclic constitutive models, anisotropic models, noncoaxial models, gradient models, compaction bands (a form of volumetric strain localization and strain localization under dynamic conditions), and the instability of unsaturated soils.
The text also includes applications of computational modeling to large-scale excavation of ground, liquefaction analysis of levees during earthquakes, methane hydrate development, and the characteristics of contamination using bentonite. The erosion of embankments due to seepage flow is also presented.

Fusao Oka is Professor Emeritus of Kyoto University and the 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 4th international workshop on localization and bifurcation theory for soils and rocks (1997), the ISSMGE International Symposium on deformation and progressive failure in geomaterials, (1997), and the international symposium on prediction and simulation methods for geohazard mitigation (2009). He has published more than 300 papers on geomechanics and is co-author of Computational Modeling of Multiphase Geomaterials (CRC Press, 2012).
Dr. Sayuri Kimoto has been working on geomechanics as an Associate Professor of Kyoto University since 2006. She is also a Professor of Osaka Sangyo University. She specializes in elasto-viscoplastic constitutive equations of soils and the numerical analysis of multi-phase geomaterials, such as the behavior analysis of sea-bed grounds due to the production of methane gas. She is a co-author of Computational Modeling of Multiphase Geomaterials (CRC Press, 2012).
