Book Description
Experimental investigations and analyses have been performed to study the behavior of granular materials with respect to their nonassociated flow and instability under certain loading conditions. All experiments have been performed in triaxial compression and extension at high as well as at low confining pressures. Major topics that were studied include: strain localization in triaxial extension tests; drained and undrained stress-strain and strength behavior from low to high pressures in triaxial extension and compression; instability of granular materials at high pressures in triaxial compression and extension; the determination of Skempton's pore pressure parameter B at high pressures; strain rate effects of granular materials at high pressures in drained and undrained conditions; examination of the effective stress principle at high pressures; particle breakage at high pressures; behavior of sand in one- dimensional compression tests at very high pressures; determination of values of K (sub o), the coefficient of earth pressure at rest, at high pressures; evaluation of the elastic modulus and Poisson's ratio at high pressure levels; correlations of high pressure soil behavior with stress-dilatancy, critical state, and input energy; static instability and liquefaction of loose fine sandy slopes; stability of granular materials in post peak softening regime; instability of dilating sand; and creep effects on static and cyclic instability of granular soils.

Book Description
This study presents the results of an extensive experimental investigation of granular materials at high pressures. Among the many types of experiments performed are drained and undrained triaxial compression and extension tests with an overall confining pressure range of 0.25 to 68.9 MPa. One-dimensional compression tests up to 900 MPa axial stress level were also performed. Major topics that were studied include: strain localization in triaxial extension tests; drained and undrained stress-strain and strength behavior from low to high pressures in triaxial extension and compression; instability of granular materials at high pressures in triaxial compression and extension; the determination of Skempton's pore pressure parameter B at high pressures; strain rate effects of granular materials at high pressures in drained and undrained conditions; examination of the effective stress principle at high pressures; particle breakage at high pressures; behavior of sands in one-dimensional compression tests at very high pressures; determination of values of k sub o, the coefficient of earth pressure at rest, at high pressures; evaluation of the elastic modulus and Poisson's ratio at high pressure levels; and correlations of high pressure soil behavior with stress-dilatancy, critical state, and input energy.

Book Description
The 16th ICSMGE responds to the needs of the engineering and construction community, promoting dialog and exchange between academia and practice in various aspects of soil mechanics and geotechnical engineering. This is reflected in the central theme of the conference 'Geotechnology in Harmony with the Global Environment'. The proceedings of the conference are of great interest for geo-engineers and researchers in soil mechanics and geotechnical engineering. Volume 1 contains 5 plenary session lectures, the Terzaghi Oration, Heritage Lecture, and 3 papers presented in the major project session. Volumes 2, 3, and 4 contain papers with the following topics: Soil mechanics in general; Infrastructure and mobility; Environmental issues of geotechnical engineering; Enhancing natural disaster reduction systems; Professional practice and education. Volume 5 contains the report of practitioner/academic forum, 20 general reports, a summary of the sessions and workshops held during the conference.

Book Description
The objectives of the experimental investigations being reported here were to further study the factors that control the stability and instability of frictional materials. The study is divided into two parts: (1) Conditions for Instability, in which a coarse sand was tested at a total of three void ratios to study effects of density as well as additional aspects of instability of granular materials. These experiments were conducted in high pressure triaxial equipment (cell pressures up to 70 MPa). (2) Creep in Sand, in which a fundamental study of creep and relaxation of granular materials was performed, because time-dependent behavior has considerable influence on the stability of granular materials. The sand employed in the experiments had weak, easily crushed grains, which typically exhibit considerable creep. The experiments were performed under drained conditions in order to maintain a constant stress state. Various stress states were used to study whether the plastic potential can be used for prediction of the relative magnitudes of the inelastic creep strain increments, and to examine the effect of creep on the outward movement of the plastic yield surface. This in turn will control the conditions for instability.

Book Description
This book presents a complete and comprehensive analysis of the behaviour of granular materials including the description of experimental results, the different ways to define the global behaviour from local phenomena at the particle scale, the various modellings which can be used for a D.E.M. analysis to solve practical problems and finally the analysis of strain localisation. The concepts developed in this book are applicable to many kinds of granular materials considered in civil, mechanical or chemical engineering.
