Superplastic deformation of ice: Experimental observations
- D. Goldsby, D. Goldsby, D. Kohlstedt
- Materials Science
- 10 June 2001
Creep experiments on fine-grained ice reveal the existence of three creep regimes: (1) a dislocation creep regime, (2) a superplastic flow regime in which grain boundary sliding is an important… Expand
Friction falls towards zero in quartz rock as slip velocity approaches seismic rates
- G. D. Toro, D. Goldsby, T. Tullis
- Geology, Medicine
- Nature
- 29 January 2004
An important unsolved problem in earthquake mechanics is to determine the resistance to slip on faults in the Earth's crust during earthquakes. Knowledge of coseismic slip resistance is critical for… Expand
Viscous flow features on the surface of Mars: Observations from high‐resolution Mars Orbiter Camera (MOC) images

(10 5 –10 7 years) of the material. Our shear stress estimates of 10 � 1.5 –10 � 2.5 MPa yield strain rates on the order of 10 � 11 –10 � 16 s � 1 , which are within the superplastic flow regime of… Expand
Constitutive relationships and physical basis of fault strength due to flash heating
- N. Beeler, T. Tullis, D. Goldsby
- Geology
- 2008
[1] We develop a model of fault strength loss resulting from phase change at asperity contacts due to flash heating that considers a distribution of contact sizes and nonsteady state evolution of… Expand
Low frictional strength of quartz rocks at subseismic slip rates
- D. Goldsby, T. Tullis
- Geology
- 1 September 2002
[1] Laboratory experiments on rocks at low sliding velocity typically yield values of the friction coefficient of 0.6–0.85. Here we demonstrate that an extraordinary decrease in friction coefficient… Expand

- 14 October 2011
Extreme temperatures generated over short distances may weaken faults during earthquakes. The sliding resistance of faults during earthquakes is a critical unknown in earthquake physics. The friction… Expand
Geological evidence for solid-state convection in Europa's ice shell
- R. Pappalardo, J. Head, +8 authors D. Goldsby
- Environmental Science, Medicine
- Nature
- 22 January 1998
The ice-rich surface of the jovian satellite Europa is sparsely cratered, suggesting that this moon might be geologically active today. Moreover, models of the satellite's interior indicate that… Expand
Rheological and Thermal Properties of Icy Materials
