The Determination of Single Edge-Notched Bend Specimen Load Line Displacement from Remotely Located Sensors in Elastic-Plastic Fracture Testing



ASTM E 813 and E 1152 currently allow for the determination of specimen load point deflection from a remotely located sensor provided that machine compliance (determined from the loading portion of an unnotched bend bar) is removed. If the specimen sustains significant plastic brinelling 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 SAE 4340 were tested to compare loading and unloading machine deflection relationships.
