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 ...

Consider the following video that summarizes the usage of Mohr’s circle for determining principle components of stress and absolute maximum shear stress components. (View YouTube video instead) ...

This is combined state of stress problem where you are asked to determine the principal components of stress and the absolute maximum shear stress. Any questions? Ask (and answer) questions here.

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 ...
