Workshop: Frontiers for Hypergravity Experiments and Model Tests

Event Date

The Frontiers for Hypergravity Experiments and Model Tests workshop in 2020 was sponsored by the University of California at Davis, Center for Geotechnical Modeling with support from the International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE) Technical Committee 104 (Physical Modeling in Geotechnics).  The workshop proceedings were published as:

  • UCD/CGM-21/02 “Frontiers for hypergravity experiments and model tests” Kutter, B. L., Fragaszy, R. J., Gaudin, C., Carey, T. J., Chen, Y., De, A., Einav, I., Fourie, A., Hueckel, T., Liao, Y-T., Phillips, R., Santamarina, J. C., Soga, K., Veveakis, M., Vulpe, C., Yeh, H., and Zhuang, D. July 2021 (2.3 MB)

The workshop webpage, listed below, has been maintained for access to the workshop objectives, agenda, presentations, and resources materials.

The objectives of this workshop are:

  1. To 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.
  2. To identify the facility and instrumentation needs for these new areas.

Participants in this Workshop will come from a wide range of engineering and science disciplines with the common connection that they are interested in topics in which gravity plays a role and hyper gravity experiments and/or modeling might advance the field. Invited speakers include individuals with prior centrifuge experience, as well as others who have interests in topics where gravity-driven physics are important.  The workshop is open to other attendees, and it is expected that individuals representing major centrifuge facilities around the world, as well as individuals engaged in centrifuge testing or interested in the topic will attend.

The workshop will be virtual (ZOOM) with two, 3-hour sessions. Invited presentations consisting of a few (4-7) Power Point slides will be posted on-line at least 2 weeks prior to the first session. During the two virtual sessions, the authors of the presentations will be given time to elaborate on their presentations, comment on other posted presentations, and add other comments on the workshop topic. A panel will then discuss the presentations, followed by a general discussion by all workshop attendees. Post workshop, an executive summary will be written describing the workshop discussions and conclusions, with recommendations for centrifuge research opportunities across multiple engineering and science fields. The workshop will be recorded and available to view after its conclusion.
