Background Although wall shear stress WSS and pressure play important roles in plaque vulnerability, characteristics of the two indices in intracranial atherosclerosis ICAS have not been fully investigated yet. This study aimed to elucidate this issue by means of establishing a non-invasive computational fluid dynamics method with time-of-flight magnetic resonance angiography TOF-MRA of ...
Under relatively small shear displacement, the shear box has still space for the particles to move and deflect shear stress increases linearly with the displacement, so the initial shear stress-strain curve is relatively smooth.

This ratio was relatively constant at 0.550.65 along high and mediumdensity polyethylene surfaces for different types of
Characteristics of a Fluid. Colloquially, one thinks of fluids as only liquids, but engineering practice recognizes two types of fluids liquids and gases . Liquids and gases share some characteristics such as a lack of shear resistance that make them similarly useful but they also have differing characteristics that require an engineer to ...
79 Experimental results show that the shear behavior and strength parameter of FRG are comparable to 80 those of pure sand Disfani, et al., 2011, Ooi, et al., 2008, Wartman, et al., 2004. While typical 81 friction angle sands ranges from 28 to 38 for sands with rounded grains and from 30 to 45 for those
Previous research results show that the key factors affecting the shear strength of joint surface mainly include two aspects one is internal factors, including rough undulation characteristics of joint surface, filling characteristics, and mechanical properties of joint surface the other is the external factors, such as the stress state of the joint surface and the boundary conditions.
The main characteristics of guillotine shears. Performance is the main criterion for selecting guillotine shears. One of the main parameters is the force with which the equipment and, in particular, the knife acts on the workpiece. Thus, the average value of the power load
