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 ...

This video is an introduction to stress and strain, which are fundamental concepts that are used to describe how an object responds to externally applied loads. Stress is a measure of the distribution ...

The member shows a tensile normal component of strain in the axial x-direction and contractive normal strains in the transverse directions (due to the Poisson’s effect). The rod does NOT experience ...

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 ...

Many complex fluids, such as surfactant mesophases, network forming polymers, emulsions etc. do not flow until the applied stress crosses a certain critical value, called the yield stress. Materials ...
