President, Wyoming Test Fixtures Inc. In my October 2015 column, I compared three V-notched shear test configurations used to measure the shear stiffness and shear strength of composite materials: The ...

One theory that is used for the prediction of failure in a ductile material is the maximum shear stress theory (MSS). The basis of this theory is that failure will occur when the maximum shear stress ...

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 ...

As the name implies, the Short Beam Shear test subjects a beam to bending, just as flexural testing methods do, but the beam is very short relative to its thickness. For example, ASTM D 2344 1 ...

The fracture surface associated with ductile fracture is shown in the photograph for a low carbon steel tested at high temperature. The top photograph shows the fracture surface at the center region ...

Dilatants are a class of non-Newtonian fluids characterized by their ability to transition from a fluid state to a near-solid state under shear stress due to a high concentration of solid particles ...
