In this paper, dissimilar resistance spot welding of AISI 1075 eutectoid steel to AISI 201 stainless steel is investigated experimentally. For this purpose, the experiments are designed using response surface methodology and based on four-factor, five-level central composite design. The effects of process parameters such as welding current, welding time, cooling time and electrode force are inv...
Platelet adhesion to vascular subendothelium under conditions of high shear stress is mediated by the platelet glycoprotein (GP) Ib-von Willebrand Factor (vWF) interaction. The aim of this study was to characterize the murine monoclonal antibodies (MoAbs) 27A10 and 28E6, both raised against purified GPIb. The MoAb 27A10 is a potent inhibitor of shear-induced platelet adhesion to collagen type I...
Background: The interaction between the blood and the vessel wall is of great clinical interest in studying cardiovascular diseases, the major causes of death in developed countries.Objective: To understand the effects of incorporating fluid-structure interaction into the simulation of blood flow through an anatomically realistic model of abdominal aorta and renal arteries reconstructed from CT...
Internal erosional behaviour of lignosulfonate treated dispersive clay has been studied using the Process Simulation Apparatus for Internol Crack Erosion (PSAICE) designed and built at UOw. Effectiveness of Iignosulfonate treated dispersive clay on the erosion resistance has been investigated and its advantage over traditional admixtures is presented. Test results show that the hydraulic shear ...
Reduced web section beams in shear-yielding moment-resistant steel frames are used for energy dissipating of earthquakes. The finite element analysis indicates that failure mode of these beams are governed by the combination of shear force and flexural moment. Therefore the analysis of frames with reduced web section beams needs consideration of shear-flexural interaction in those sections. In ...
This research presents, buckling and free vibration analysis of fiber metal-laminated (FML) plates on a total and partial elastic foundation using the generalized differential quadrature method (GDQM). The partial foundation consists of multi-section Winkler and Pasternak type elastic foundation. Taking into consideration the first-order shear deformation theory (FSDT), FML plate is modeled and...
Bed-load transport is effective on river bed stability and Morphology. Therefore, modeling this phenomenon is very important in the field of hydraulics engineering. Bed-load transport occurs by saltation at low to medium shear stress and by sheet-flow at high shear stress. In the present paper, the hydrodynamics of transport in thesaltationand sheet-flow regimes under unidirectional flow is stu...
For regions of partial melt in the lower mantle, both compressional and shear wave velocities decrease monotonically with increasing melt volume fraction. It has been observed that regions close to the core-mantle boundary thought to contain partial melt have a velocity decrement ratio (relative change in shear velocity over relative change of compressional velocity) of about 3. This is certain...
Understanding critical layers in stratified shear flow instabilities: A wave interaction perspective
In this paper we examine the dynamics of unstable critical layers in stratified shear flows. This is done from the framework of the wave interaction theory of shear instabilities, which views instability as arising from the mutual interaction between wave motions that are present in the background shear and density fields. By formulating a simple analytical model of the structure of vorticity w...
The dissociation of dislocations in the NaCl structure is discussed in terms of Fontaine's model. There are no well-defined partials in the dissociation of the Burgers vector a/2 [I101 on the (1x0) slip plane. The stacking fault on this plane is connected with a dilatation normal to (170). This leads to an unique effect of hydrostatic pressure on the frequency of cross slip. Cross slip in stage...
