8th International Symposium on Deformation Characteristics of Geomaterials

The Technical Committee on Laboratory Stress-Strain-Strength Testing of Geomaterials (TC101) of the International Society of Soil Mechanics and Geotechnical Engineering (ISSMGE), endorsed by the Portuguese Geotechnical Society (SPG) and the Faculty of Engineering of the University of Porto (FEUP), invite you to participate in IS-PORTO 2023: 8th International Symposium on Deformation Characteristics of Geomaterials to be held from the 3rd to the 6th September 2023 in Porto. IS-Porto 2023 aims to continue the success of previous symposia: Hokkaido 1994, Torino 1999, Lyon 2003, Atlanta 2008, Seoul 2011, Buenos Aires 2015 and Glasgow 2019. This symposium will focus on the understanding of the deformation properties of geomaterials before failure, especially on the small-strain stiffness parameters as fundamental characteristics of geomaterials, and their implications in geotechnical design.

Topics: Experimental investigations from very small strains to beyond failure - Advances in laboratory testing techniques (equipment and procedures). - Advances in field testing and monitoring techniques. - Advanced sampling. - Data interpretation and geotechnical imaging. - Multiscale problems in geomechanics (micro‐to‐macro strains). II. Behaviour, characterization and modelling of various geomaterials and interfaces - Constitutive modelling of geomaterials. - Physical and numerical modelling. - Anisotropy and localisation. - Time-dependent response. - Cyclic and dynamic behaviour. - Soil stabilisation and improvement. - Thermal behaviour. - Non-textbook soils: intermediate soils (partially drained, etc). - Sensitive and liquefiable soils: tailings and other highly brittle strain-softening soils. - Frozen soils. - Soil-plant interaction. III. Practical prediction and interpretation of ground response: field observation and case histories - Integrated site characterization: derived values to be actually used in the design. - Performance evaluation of geotechnical structures: how to improve our understanding of our “affordable” test methods that typically measure something else (hopefully reasonably related). - Field monitoring and observational method: new systems for measuring deformations in support of alert-to-alarm criteria.
