This e-book offers contributions to the ninth overseas Workshop on Bifurcation and Degradation in Geomaterials held in Porquerolles, France, may well 23-26, 2011. This sequence of meetings, began within the early Nineteen Eighties, is devoted to the study on degradation and instability phenomena in geomaterials.
The quantity gathers a chain of manuscripts via marvelous foreign students reflecting contemporary developments in theoretical and experimental examine in geomechanics. It contains contributions on subject matters like instability research, localized and diffuse failure description, multi-scale modeling and purposes to geo-environmental issues.
This e-book could be necessary for an individual drawn to the examine on degradation and instabilities in geomechanics and geotechnical engineering, attractive to graduate scholars, researchers and engineers alike.

Through the obtained results, the strain localization behavior in partially saturated sand is discussed by comparing the results with those for fully saturated sand and air-dried sand specimens. Furthermore, the microstructure of partially saturated sand is viewed in a partial CT scan, namely, a part of the specimen of interest is scanned with high magnification. In particular, focus is placed on the microstructures in shear bands. 2 Material and Methods The test sample used in this study is Toyoura sand.

Mech. Mater. 41, 715–728 (2009) F. E. Wolf, M. J. Moreau, Bimodal character of stress transmission in granular packings. Phys. Rev. Lett. S. -Y. -Y. Hicher Abstract Instability of sand can occur under drained or undrained loading conditions in loose sand or dense sand. A micromechanics approach is used for the analysis of local instabilities of inter-particle contacts and their relations to the global instability of assembly. The comparisons between experimental and predicted results on Toyoura Sand show the capability of the model in capturing the modes of instability at the assembly level.
