Dilatancy and Fracture Induced Velocity Changes in Rock and their Relation to Frictional Sliding,ity decreases remarkably in the directions of minor principal stresses with no indication for velocity recovery before macroscopic shear fracture development..The results suggest that dilatancy and velocity anomalies may precede crustal earthquakes under certain tectonic conditions.神化怪物 发表于 2025-3-30 16:27:08

Time-Dependent Friction and the Mechanics of Stick-Slip, to change the population of contacts and the slip velocity. An analysis of a one-dimensional spring and slider system shows that experimental observations establishing the transition from stable sliding to stick-slip to be a function of normal stress, stiffness and surface finish are a consequence of time-dependent friction.Jogging 发表于 2025-3-30 23:07:58
,Editors’ Note,learly zones of weaknesses in the crust. On the other hand, some laboratory tests at high pressure indicate that the frictional strength of faults approaches the fracture strength of intact rocks. Therefore some of the major questions are: How is friction along fault planes overcome? Are the local s公司 发表于 2025-3-31 01:04:50
A Review of Rock Mechanics Studies in the United States Pertinent to Earthquake Prediction,oment, and gas emission, which occur before fracture of initially intact rock and before stick-slip on faults or between finely ground surfaces of rock, have been reviewed and discussed in relation to earthquake prediction. This review is restricted to the results of laboratory experiments that haveAWRY 发表于 2025-3-31 06:07:35

Friction of Rocks, between experiments. This is because at low stress rock friction is strongly dependent on surface roughness. At high normal stress that effect is diminished and the friction is nearly independent of rock type.

The Effect of Water on Stress Relaxation of Faulted and Unfaulted Sandstone,rength at different strain rates. Temperatures employed were 20, 300 and 400°C, effective confining pressure was 1.5 kb and strain rates as low as 10. sec. were achieved. Most samples were prefaulted at 2.5 kb confining pressure and room temperature. This is thought to have secured a reproducible indowagers-hump 发表于 2025-4-1 01:24:59
