Some non-Newtonian fluids will thicken—increase viscosity—when a shear stress is applied, as in stirring. This is called shear-thickening. Others get less viscous, which is called shear-thinning. But ...

Short Beam Shear is an excellent materials screening and quality control test, particularly if a unidirectional composite can be tested. Though this method obtains neither a pure nor uniform shear ...

Although the stress state in the short beam is not the pure shear that would be desired in an ideal shear test method, there are some redeeming features. Away from the loading and support points, the ...

ASTM D3518 establishes the in-plane shear response of polymer matrix composite materials by a tensile shear test. Properties calculated include the shear modulus, shear stress, shear strain, and chord ...

One of the most critical, yet often underestimated variables, is shear stress. While controlled shear stress can be useful in simulating physiological conditions, unintended shear forces – especially ...

The destruction of red blood cells, or mechanical hemolysis, is an inevitable complication of interventional devices, so scientists want to gain a better understanding of the phenomenon.

Seepage stress changes were determined by analyzing collapsing pressure at different azimuth angles (Fig. 5). In some parts of azimuth (20-50° and 160-270°), seepage stress change has very ...

Panel B shows that fluid shear stress (shown in a cross section of a blood vessel) is normal upstream of the stenosis (10 to 20 dyn•cm −2), increasing to pathologically high stress (>100 dyn ...
