Threaded Rod Tensile Testing
Threaded Rod Tensile Testing
(OP)
I want to do a standard tensile test on a A36 threaded rod (1"-8 threads). I was planning on threading large steel plates to the top and bottom of the rod so that the tensile tester can clamp onto these plates for easier mounting. Is there a way to calculate the minimum thread engagement length needed to ensure that the rod is not stripped out of the threads before the rod breaks? A36 steel has a tensile strength between 58 and 80 ksi.

Further, you buying an "average" (or maybe a cheap Chinese imitation!) of an "average" A36 piece of steel. What is its actual strength? Are you sure you really know the baseline strength of what you "think" "should be" 36,000 psi?
At this level of calculation - you also need to actually measure the diameter and actual thread depth. Don't "assume" your book values are correct.
