    Abstract

    The experience of the authors with the automation of the fatigue crack growth experiment is described. The system is described from both the hardware and the software standpoints.

    The approach used in automating the fatigue crack growth experiment was to make as much use of the computer as possible by writing large, user friendly, multipurpose program systems. The approach has been very successful based on four years of experience in conducting experiments. High quality results have been obtained from experiments conducted by personnel not skilled in computer programming.
