Controlled-Strain Testing Procedures


Experimental procedures are described for conducting fatigue investigations at high temperatures on servo-controlled testing machines. Specially developed equipment permits programming of push-pull tests on hourglass specimens with closed-loop control of either stress, axial strain, transverse strain, or plastic strain at the minimum diameter of the specimen.
