Distributed shear apparatus experiments using semi-brittle analog Carbopol Ultrez 21

Journal of Geophysical Research - Solid EarthTitle: The impact of rheology on the transition from stick-slip to creep in a semi-brittle analog (Published)Authors: Thomas Birren and Jacqueline E. ReberAffiliation: Department of Geological and Atmospheric Sciences, Iowa State University, Ames, IA 50011<br>This data set contains distributed shear apparatus experiments using semi-brittle analog, Carbopol Ultrez 21 at concentrations of 1, 2, and 3 wt.%. Measurements of pulling force and displacement show the slip behavior of the material ranges from stick-slip to creep for concentrations from high to low. Additionally, we provide particle image velocimetry outputs from PIVlab (a Matlab application) containing vectorized data of flow in our experiments. Original top-looking-down, time-lapse photographs are included where fracture morphology can be easily observed.
