Preface

IS-Grenoble 2024, the 5 th International Symposium on Geomechanics from Micro to Macro , was organized under the auspices of Technical Committee 105 (Geomechanics from Micro to Macro) of the International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE). The preceding symposia were held at Yamaguchi University, Japan in 2006, Tongji University, China in 2010, Cambridge University, England in 2014, and Georgia Tech, USA in 2018. As with these previous events, this symposium aimed to advance the objectives of TC 105, which are to: • promote cooperation and the exchange of information about the behavior of soil grains and granular interactions; • promote improved modeling of soil aggregates; • encourage a microstructural understanding of significant macroscopic behavior; • facilitate discussions on the use of microstructural measurements to enhance soil characterization procedures; • clarify the selection and use of continuum parameters in geotechnical engineering practice. IS-Grenoble 2024 took place under the patronage of ALERT-Geomaterials, the European association for Education, Research and Technology in Geomechanics. The symposium gathered 269 attendees, featured 96 oral and 90 poster presentations, and included 14 sessions devoted to: Numerical Modeling, Imaging, Below the micron, Innovations in Numerical Modeling, Experimental Methods, Unsaturated Materials, Dialog between experiments and modeling, Microstructure characterization, New trends in modeling, Theoretical developments, Damage/thermal behavior, Experimental Imaging, and Continuum modeling. Additionally, a plenary session was devoted to the DEM Round Robin Test organized by TC 105.
