Abstract: Methods are provided for joint performance validation and include preparing a coupon from a blank by bending the blank to have a pair of legs disposed at substantially ninety degrees relative to each other. Another coupon is prepared by forming an opening in a segment of another blank and bending the segment approximately ninety degrees. The segment is disposed adjacent an end of the second blank. A test sample is prepared by joining the coupons together at a joint with a leg attached to the segment approximately at a center of the leg. The test sample is subjected to a force test to generate data for the performance validation.
