argh.. I'll just take the possible explanations I found researching and present it to my boss. Thanks anyway.

I looked up pure bending. How can there be no tensile stress in pure bending when there is a compression and tension component to pure bending?

The diameter was 0.236 inches. 36mm between supports of the 3 point bend setup. I used an MTS test machine. The MTS machine plotted the graph. From the graph, I found the ultimate load then calculated the stress: 32*((758 lb * 1.42 in)/4) /(pi*.236 in ^3 ) I got the yield load from...

Matt, can you point to a resource that explains that comparing them would be like comparing apples to oranges? That is part of my question, Shouldn't the same material provide the same strength when tested under these two conditions especially considering that the failure mode at the...

This is more of a theoretical question. Not sure if this should be under this section or Mechanical Engineering. Homework Statement For 1018 steel, I tested the UTS to be about 83 ksi for a dogbone specimen with a circular cross-section. However, when I determined the Ultimate Bending...
