The traditional method for determining yield stress on a rotational rheometer or viscometer was by fitting models to the measured rheograms and extrapolating to zero shear rate. This article discusses ...

Discover why low-density polyethylene (LDPE) samples with identical melt flow rates (MFR) can still show varying viscosity ...

Journal of Coastal Research, Special Issue 64: PROCEEDINGS OF THE 11th INTERNATIONAL COASTAL SYMPOSIUM ICS2011 (2011), pp. 2007-2011 (5 pages) The estimation of the bed shear stress is a crucial step ...

The transverse load P will produce a shear force V in the positive y direction on a mathematical cut through the beam at point “a”. This shear force is directly responsible for the shear stress τ on ...

“Clot-busting” fibrinolytic drugs are administered to patients who have had a heart attack or ischemic stroke. These drugs are delivered systemically or, when possible, locally through a catheter ...

Fluid flow stimulates bioluminescence in dinoflagellates. However, many aspects of the cellular mechanotransduction are incompletely known. The objective of our study was to formally test the ...

Water is ubiquitous and seemingly ordinary, possessing no distinct color or odor. Though we often take water for granted, it is by no means a simple substance. As a consequence of its chemical ...

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. Researchers ...

Here is a short introduction into bearing, shear and tear-out stresses in bolted joints and how complex they can be. Jointing is a basic function of engineering. For example, bolting two parts ...

Say we consider a beam made up of thin layers (laminae) aligned with the longitudinal axis of the beam, and for which the laminae can slide with respect to each other along the longitudinal axis as ...
