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 ...

Study hints at the potentially crucial role of shear stress in ... School and Worcester Polytechnic Institute have recently set out to better understand these mechanisms by conducting experiments ...

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 ...

Zhou illustrates this adaptability, noting that under shear stress, PAMs behave like water with “zero resistance,” due to ...

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 ...

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.

A bending stress on a beam can increase tensile and shear stresses on the bolts. (For a way to visualize bending in a beam, see “What’s the Difference Between Beam Diagrams?” Tear-Out ...

The authors wrote, "For generations, based on Glen's original experiments and many subsequent experiments mostly on cold ice (-2 degrees C and colder), the value of the stress exponent n in models ...
