Report on Bending Stress Relaxation Round Robin

Source

Three laboratories participated in a bending stress relaxation, round robin, test program. Elastic springback, continuous force measurement, and lift-off methods were used to determine stress remaining. Cold-rolled copper alloys CDA 110 (ETP copper) and CDA 260 (70-30 brass) at thicknesses of 0.05, 0.1, and 0.25 cm were utilized. All tests were conducted at 105°C up to about 200 h according to the ASTM Recommended Practice for Stress Relaxation Tests for Materials and Structures (E 328-75). The results show that the agreement among the three methods is quite good.
