Effects of shear heating and dilatancy on slip instability of a fluid-infiltrated fault with rate/state depen- dent friction
where the expression following the first equality is the force in the spring and that following the second is the frictional resistance to sliding of the block (both expressed for a block of unit area). The load point velocity vo is the product of the imposed rate of tectonic strain rate γ̇ in the crustal block and the characteristic length of the block. The effective spring stiffness k is the s...
متن کاملUsing IRSL to determine the slip rate of the Doruneh fault in Khalilabad
Introduction The left lateral Doruneh Fault System (DFS), is one of the longest, and most prominent, strike-slip faults in Iran, extending from the eastern border of Iran to the central Dasht-e-Kavir with a curved geometry. DFS is the response of the convergence between the Arabian and Eurasian plates in the regional tectonic map. Regarding to scaling relationships this fault with length of ...
متن کاملSlip-rate measurements on the Karakorum Fault may imply secular variations in fault motion.
Beryllium-10 surface exposure dating of offset moraines on one branch of the Karakorum Fault west of the Gar basin yields a long-term (140- to 20-thousand-year) right-lateral slip rate of approximately 10.7 +/- 0.7 millimeters per year. This rate is 10 times larger than that inferred from recent InSAR analyses ( approximately 1 +/- 3 millimeters per year) that span approximately 8 years and sam...
متن کاملThe distributions of slip rate and ductile deformation in a strike- slip shear zone
A simple mechanical model and dimensional analysis are used to derive a scaling law for the partitioning between slip rate on a strike-slip fault and distributed deformation in the far-field. The depth of the fault, the distributions of stress, strain rate and slip rate are solved for a given far-field force or displacement in a 2-D medium with a linear temperature-dependent viscous rheology. A...
متن کاملPermeability of textile reinforcements: Simulation, influence of shear and validation
The permeability of textile reinforcements is a crucial input for the simulation of the impregnation stage of a composite material fabrication process. In this paper, we present a fast and accurate simulation method for the permeability of a textile reinforcement, based on a finite difference discretisation of the Stokes equations. Results for single layer, multi-layer and sheared models are di...
