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 ...

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 ...

In a world where software analysis has taken over, let us take a history lesson to remember what makes our finite-element-analysis (FEA) software tick. Morh’s circle is just a graphical representation ...

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 ...

The stress value then levels off at the equilibrium value (Figure 7). Figure 7. Illustration showing the stress evolution of a yield stress material at constant shear rate. Normally, a low value of ...

The Iosipescu Shear and the V-Notched Rail Shear test methods are ASTM standards, ASTM D 5379 1 and D 7078 2, respectively. Both are used primarily for in-plane shear testing, but each can be used for ...

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 ...
