In this book, a systematic investigation, including laboratory test, theoretical modeling, and numerical analysis, was carried out to study the deformation behavior of sand. In the experimental investigation, a series of laboratory tests, including triaxial compression and extension tests, torsional shear tests, and resonant column tests, was performed to investigate the comprehensive behavior of Leighton-Buzzard sand under various loading and drainage conditions. Based on the test results, a unified sand model, established within the framework of the state dependent dilatancy and the concept of crotical state, was calibrated. The responses of sand in tests were simulated with this calibrated model. The verified model with the calibrated model constants was then used in a fully coupled finite element procedure to investigate the shear band formation in plane strain condition.
This book will promote the modeling of sand, and I believe that it will be of great interest to geotechnical researchers and practitioners.
