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 ...

Consider the following four examples of states of plane stress. Can you construct the Mohr’s circle for these examples? Can you determine the principal components of stress? Can you determine the ...

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 ...

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 ...

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 ...
