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 ...

Jointing is a basic function of engineering. For example, bolting two parts together can involve material properties and loading forces. Here, we will focus on preloading, shear and tear-out in a ...

The offset shear strength is the shear stress endured by a material at the intersection of the shear stress versus the engineering shear strain curve, with a line parallel to a defined modulus and ...

President, Wyoming Test Fixtures Inc. The test fixtures and specimens used for the three methods are compared in Fig. 1, at left. All three apply an asymmetrical four-point bend loading to the ...

The term thixotropy consists of the Greek words "thixis" (touch) and "trepein" (to turn). It means change or transition due to mechanical load. In rheology thixotropic behavior is defined as ...
