Abstract
ASTM E 813 and E 1152 currently allow for the determination of specime n load point deflection from a remotely located sensor provided that m achine compliance (determined from the loading portion of an unnotched bend bar) is removed. If the specimen sustains significant plastic br inelling at the load points, the result is a nonconservative estimate of deflection (and J) subsequent to maximum load. A procedure for the determination of machine compliance relationships for both loading and unloading conditions is presented. Unnotched bend bars of tempered SA E 4340 were tested to compare loading and unloading machine deflection relationships.
