A Data Acquisition and Control Program for Axial-Torsional Fatigue Testing
Abstract
A computer program was developed for data acquisition and control of axial -torsional fatigue experiments. The mult-tasked, interrupt-driven program is capable of dual-channel control and six-channel data acquisition. It can be utilized to perform inphase and out-of-phase axial-torsional isothermal fatigue or deformation experiments. The program was successfully used to conduct inphase axial torsional fatigue experiments on 304 stainless steel at room temperature and on Hastelloy X 800 C. This paper describes the details of the software and gives some of the results generated to date. Failure of engineering components due to fatigue is a common occurrence in the aerospace and automotive industries. It is therefore necessary to characterize the fatigue behavior of materials so that the engineering components can be operated safely and reliably.
