IS-ATLANTA 2008

Fourth International Symposium on Deformation Characteristics of Geomaterials (IS-Atlanta 2008)

Scheduled: 22-24 September 2008 - Global Learning Center
Georgia Institute of Technology, Atlanta, Georgia, USA

The Geosystems Engineering program at the Georgia Institute of Technology together with ISSMGE Committee TC-29 of ISSMGE (Laboratory Stress-Strain-Strength Behavior of Geomaterials) are pleased to announce the 4th International Symposium on Deformation Characteristics of Geomaterials (IS-Atlanta 2008). The event is co-sponsored by TC16 - In-Situ Testing. This event builds on the success of previous symposia: IS-Hokkaido 1994, Symposium in Print - Geotechnique (London, 1997), IS-Torino 1999, and IS-Lyon 2003. The papers presented at these symposia have had a significant influence on the understanding of the deformation properties of soils and rocks, particularly noting the small strain shear modulus (Gmax) as a fundamental stiffness of geomaterials. The proceedings of this upcoming symposium on the topic have been produced in two hard-bound volumes and CD versions by Millpress-IOS as an invaluable reference document in geotechnical engineering with 9 keynote talks and 93 technical presenters all in plenary session. The international symposium attracted 141 participants for this premier event.

Broad Themes

1. Field characterization techniques – focus on new and innovative in situ methods for measuring deformation properties of soils and the use of complementary methods for characterization of soil behavior over a broad range of strain levels
2. Laboratory characterization techniques – focus and new and innovative laboratory methods for measuring deformation properties of soils
3. Numerical methods – focus on the development, calibration and use of numerical methods including FEM, FD, strain path, and discrete element techniques

Focused Themes

1. Small-strain stiffness of geomaterials, including effects of anisotropy, strain rate, ageing, lab-field comparisons, and modulus reduction behavior
2. Influence of discontinuities on deformation properties – shear bands, compaction bands, desiccation fractures, ice lensing, and polygonal faults
3. Influence of spatial variability on deformation properties – the effects of spatial variability and anisotropy on the deformation response of soils
4. Deformation properties of improved soils – the deformation properties of treated soils or soils with man-made inclusions
5. Performance-based geotechnical engineering – design approaches and case studies focusing on performance-based geotechnical engineering
