the 1" section is just a v notch, i want the part to fail at the notch. I will not be measuring the stretch of the part with any type of device. I just want to know roughly how much the overall lenght of the test peice will increase before the failure occurs at the notch.
full size test of final part,
now if the diamter of the specimen was uniform throught i would agree that it would strethc roughly 6"
however there is a notch which brings it down to 1" in the center.
so does this mean that the length i should use in teh equation is the length of which the...
I am performing a destructive test in which i will be pulling a very long tensile test specimen.
the speicimen is 63" long with a diamter of 1.5", at the midpint of the specimen it will be notch with a diamter of 1 " .
the materail is a AISI 4340 alloy steel with a min yield of 150 KSI.
