The material in this work is focused on recent developments in research into the stress-strain behavior of geomaterials, with an emphasis on laboratory measurements, soil constitutive modeling and behavior of soil structures (such as reinforced soils, piles and slopes). The latest advancements in the field, such as the rate effect and dynamic behavior of both clay and sand, behavior of modified soils and soil mixtures, and soil liquefaction are addressed.

This book is an outgrowth of the proceedings for the Geotechnical Symposium in Roma, which was held on March 16 and 17, 2006 in Rome, Italy. The Symposium was organized to celebrate the 60th birthday of Prof. Tatsuoka as well as honoring his research achievement. The publications are focused on the recent developments in the stress-strain behavior of geomaterials, with an emphasis on laboratory measurements, soil constitutive modeling and behavior of soil structures (such as reinforced soils, piles and slopes). The latest advancement in the field, such as the rate effect and dynamic behavior of both clay and sand, behavior of modified soils and soil mixtures, and soil liquefaction are addressed. A special keynote paper by Prof. Tatsuoka is included with three other keynote papers (presented by Prof. Lo Presti, Prof. Di Benedetto, and Prof. Shibuya).

Geomechanics: Testing, Modeling, and Simulation gathers the most state-of-the-art geomechanics research conducted by investigators from the United States and Japan. This book contains papers presenting new data, methods, and facilities on a variety of topics in the areas of testing, modeling, and numerical simulations in geomechanics. A wide range of research is incorporated into the text, which is divided into eight sections: time effects; stress-strain behavior and cyclic loading residual strains; anisotropy and fabric bonding; shear banding and postpeak stress-strain behavior; liquefaction; effects of particle size, gradation, and particle breakage; new testing equipment and systems; and innovative computational methods. Included is an appendix of discussion notes, which were recorded upon the papers' presentation. Those with an interest in the current trends and research topics in geomechanics in the United States and Japan will find this book extremely beneficial.
