Biography

Teruo Nakai is a professor at the Nagoya Institute of Technology. He has received several honors, including Best Research Paper Awards from the Japanese Geotechnical Society. He earned a Ph.D. from Kyoto University. His research interests include the testing of geomaterials and their constitutive modeling in general stress systems as well as the application of constitutive models to boundary value problems, such as tunneling, braced excavation, bearing capacity of various foundations, and reinforced soils.

"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."
