Velocity ®eld for the trishear model
نویسندگان
چکیده
A general method for the derivation of velocity ®elds consistent with the basic kinematics of the trishear model of faultpropagation folding is given. We show that the ®elds can be written as explicit functions of position within the deformation zone. To demonstrate the approach, several dierent linear and non-linear velocity ®elds are derived and plotted. We show that the trishear zone need not be symmetric and that the trishear model produces 1/r singular strain rates, consistent with results for cracks in elastic±plastic materials. A continuous formulation of heterogeneous trishear is also presented. 7 2000 Elsevier Science Ltd. All rights reserved.

EXACT SOLUTIONS FOR FLOW OF A SISKO FLUID IN PIPE
By means of He's homotopy perturbation method (HPM) an approximate solution of velocity eld is derived for the ow in straight pipes of non-Newtonian uid obeying the Sisko model. The nonlinear equations governing the ow in pipe are for- mulated and analyzed, using homotopy perturbation method due to He. Furthermore, the obtained solutions for velocity eld is graphically sketched...

Background: According to the drug resistance and side effects of the standard treatments for leishmaniasis, achieving effective treatment with less side effects and more benefits is of paramount importance. The present study aimed to evaluate the effect of Aloe vera leaf exudate on Leishmania major under in vitro and in vivo models, in inbred BALB/c mice. Methods: Different concentrations of bo...
متن کاملVisualization of Black Hole Based on Computational Relativistic Fluid Dynamics
Visualization of a \ eld", which is a physically invisible concept, is a main subject of scienti c visualization. In this paper described is a method for visualizing a great gravitational eld like a black hole. We assume a velocity vector eld of imaginary uid in the vicinity of the black hole for its e ective visualization. We describe the eld by using equations so called \Eulerian method". Thi...
متن کاملA universal velocity ®eld for the extrusion of non-axisymmetric rods with non-uniform velocity distribution in the extrusion direction
This study formulates a universal velocity ®eld that is kinematically admissible for application in the extrusion of non-axisymmetric rods. Then upper bound theorem dictates that a better upper bound solution heavily depends on the precise conformity of the velocity ®eld postulated. However, a compromise must frequently be made, since the formulation is in general rather complicated. The kinema...
متن کاملAn Efficient Meta Heuristic Algorithm to Solve Economic Load Dispatch Problems
The Economic Load Dispatch (ELD) problems in power generation systems are to reduce the fuel cost by reducing the total cost for the generation of electric power. This paper presents an efficient Modified Firefly Algorithm (MFA), for solving ELD Problem. The main objective of the problems is to minimize the total fuel cost of the generating units having quadratic cost functions subjected to lim...
