Centrifuge modeling of earthquakes [PDF]
Geophysical Research Letters, 1978 The major problem in scale modeling of crustal tectonic processes, namely, the requirement for a brittle modeling material of extremely low strength (∼0.1 bar) can be overcome by doing model tests under artificial gravity in a centrifuge. When conditions of dynamic similarity are observed, scale modeling, because of its controlled nature, can be an ...

Scaling principles of debris flow modeling using geotechnical centrifuge
Yantu gongcheng xuebao, 2019 The scale effect of debris flow hinders the in-depth understanding of debris flow dynamics. The geotechnical centrifuge can replicate the appropriate stress states of the prototype through an equivalent elevated centrifugal acceleration field.

Technical Note: The use of an interrupted-flow centrifugation method to characterise preferential flow in low permeability media [PDF]
Hydrology and Earth System Sciences, 2015 We present an interrupted-flow centrifugation technique to characterise preferential flow in low permeability media. The method entails a minimum of three phases: centrifuge-induced flow, no flow and centrifuge-induced flow, which may be repeated several
