I am trying to identify a failure on a part that was designed by others and we see intermitent shearing failures during a torque test that we perform in our assembly process. One shipment will have 0.5% failures and the next months shipment will show 11%. I am trying to determine if we should...
I have a round shaft that will be made out of plastic material and cannot find a consistent property to use for determination of material. For example, my part will have a max shear stress of 6,800 psi and I am looking at a nylon material that shows a break tensile of 16,000 psi. Any input...
