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.

Soil Constitutive Models: Evaluation, Selection, and Calibration brings together papers by nineteen of the most significant constitutive modelers in the world today. The papers in this ""ASCE Geotechnical Special Publication"" are focused on existing widely accepted soil constitutive models, from simple to complex, and they present the overall model framework, calibration procedures, and possible implementation. As a guide to the reader, an overview paper discusses features of different classes of soil models, and their advantages and disadvantages. For many models in this book and in the literature, these features are tabulated in a series of tables. The models are then categorized in terms of their completeness with respect to eight different model capabilities. This book has been prepared for soil constitutive modelers and practitioners who want to learn more about the underlying principles, calibration methods and implementation issues of many different proven soil models. The overview paper is especially helpful to those who are not experienced constitutive modelers to understand the different components of soil models and their effect on predictions. This book provides a basis for making the appropriate decision on the selection of a soil constitutive model for any particular geotechnical engineering application.
