HYDRAULIC TENSION COMPRESSION FATIGUE MACHINE,
Abstract
A tension - compression fatigue machine was de signed and built which permits fatigue testing under controlled uniaxial stress or strain ampli tudes with zero, positive or negative mean stress or strain amplitudes with zero, positive or neg ative mean stress or strain. stress or strain amplitudes can be varied continuously during a test in order to perform increasing stress or strain amplitude fatigue tests. Recording of the stress or strain levels and of the stress strain hysteresis loops is done by means of an oscilloscope and/or an X-Y recorder. The hydrau lic system, the instrumentation and the command, control and read-out electronic systems are described in cdetail. Some results which are rep resentative of the applications of the fatigue machine are described. (Author)
