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 ...

Stress is defined as the force per unit area. Thus, the formula for calculating stress is: Where σ denotes stress, F is load and A is the cross sectional area. The most commonly used units for stress ...

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 ...

A new study uses shear tests and seepage-stress analysis in north China's Liushagang formation to create a model that predicts collapsing pressure and avoids costly drilling delays in hard, brittle ...

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 ...

In physics, shear stress is a stress state in which the shape of a material tends to change (usually by "sliding" forces -- torque by transversely-acting forces) without particular volume change.
