Centrifuge Workshops

The UC Davis NHERI Experimental Facility hosted the 7th Centrifuge Users Workshop on October 12-13, 2023. The workshop was a hybrid remote/in-person event similar to the previous year.  The mornings of both days comprised presentation and discussion sessions for both the remote and in-person participants. The afternoons comprised working sessions for in-person participants. The presentation/discussion sessions in the mornings covered (1) the NHERI centrifuge facility science plan and capabilities, (2) principles of centrifuge modeling, (3) centrifuge test design and planning, (4) external user experiences, and (5) example research projects. Links to PDFs of the morning presentations are provided below. The working sessions for in-person participants in the afternoons focused on proposal development and included interactive sessions on (1) further developing a research vision, (2) designing and planning a centrifuge test program, and (3) writing a proposal for research using the NHERI centrifuge facility.

The UC Davis NHERI Experimental Facility hosted virtually the 5th Centrifuge Users Workshop on October 28-29, 2021. The workshop inlcuded a virtual tour and lectures describing the capabilities of the centrifuge facility, various research opportunities and challenges, guidance on preparing research proposals, and details about planning, budgeting, and scheduling of experimental programs. Breakout sessions provided opportunities for discussion of specific research details or questions posed by participants. The program, with links to PDFs of presentations where applicable, was as follows.

The UC Davis Center for Geotechnical Modeling / NHERI Experimental Facility hosted an International Workshop on "Frontiers for Hypergravity Experiments and Model Tests" in December 2020 with support from the International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE) Technical Commitee on Physical Modeling in Geotechnics. The objectives of the workshop were to: (1) identify and make the case for new, underutilized, and emerging areas of research across engineering and the sciences that might benefit from the use of a centrifuge, and (2) identify the facility and instrumentation needs for these new areas.
