Description

Winner of the Japanese Geotechnical Society 2016 publication award

Written by a veteran geotechnical engineer with a long record of research discoveries, Constitutive Modeling of Geomaterials: Principles and Applications presents a simple and unified approach to modeling various features of geomaterials in general stress systems. The book discusses the fundamentals of the constitutive modeling of soils and illustrates the application of these models to boundary value problems.

Helping readers easily understand the fundamentals and modeling of soil behaviors, the author first explains the ideas and formulations for modeling soil features in one-dimensional conditions. He then extends the one-dimensional models to three-dimensional models using the tij concept. The text covers the subloading tij model and other methods that describe density, bonding, time effect, and more. Moving on to the practical application of the constitutive models, the author presents the numerical simulations of typical geotechnical problems (numerical modeling) and the corresponding model tests (physical modeling).

Using a framework that leads to a unified set of material parameters, this book shows how to formulate a constitutive model capable of simulating the main features of soil behavior. It not only covers recent methods and models but also uses real test data to prove their reliability.

Reviews

"The book is written in an easy-to-read style without frills. The style is typical of Prof. Nakai, namely correct, concise and complete. The line drawings and photos are well proportionated and reproduced with high quality. The access to the stuff is made easy by embarking on the 1D relationship at the beginning of the book, which makes it an excellent text-book for graduate students. However, the book is also highly recommended to experts who wish to brush up their knowledge in constitutive modeling. I enjoyed reading this book for my review and was rewarded with surprising goodies here and there. There are many details to be discovered."
