Computational Multiphase Geomechanics

Fusao Oka is a professor emeritus of Kyoto University and president of theLIQCA Liquefaction Geo Research Institute. Until 1997, he was a professorin the Department of Civil and Earth Resources Engineering of KyotoUniversity. He specializes in computational geomechanics with particularregard to constitutive equations, consolidation, liquefaction, and strainlocalization analyses. He organized several international conferences andworkshops, such as the Fourth International Workshop on Localization andBifurcation Theory for Soils and Rocks (1997), the ISSMGE InternationalSymposium on Deformation and Progressive Failure in Geomaterials (1997),the International Symposium on Prediction and Simulation Methods forGeohazard Mitigation (2009), and the 14th International Conference ofIACMAG (2014). He has published more than 300 papers on geomechanicsand is a co-author of Computational Modeling of Multiphase Geomaterials(CRC Press, 2012).Sayuri Kimoto had been working on geomechanics as an associate professorat Kyoto University for years. She is presently a professor of Osaka SangyoUniversity. She specializes in the elasto-viscoplastic constitutive equationsof soils and the numerical analysis of multiphase geomaterials, such as thebehavior 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).
