Failure boundaries and Mohr’s circle

One theory that is used for the prediction of failure in a ductile material is the maximum shear stress theory (MSS). The basis of this theory is that failure will occur when the maximum shear stress ...

The short beam shear test

As the name implies, the Short Beam Shear test subjects a beam to bending, just as flexural testing methods do, but the beam is very short relative to its thickness. For example, ASTM D 2344 1 ...

Becoming familiar with Mohr’s circle

Mohr’s circle is a convenient means by which we can visualize the results of the stress transformation relationships for a state of plane stress. Recall that in order for us to draw Mohr’s circle, we ...
