Recently mini- or micro-computers are widely used even in the field of fatigue or fracture tests. The main purpose of their use, however, are automization of testing or measurements. In this study an automatic measurement system for fatigue tests has been developed by using mini-computers in consideration of detecting the parameters which control the fatigue process. The stress-plastic strain hysteresis loop and the crack opening point were measured as the controlling factors during the fatigue process up to the crack initiation and during the crack propagation stage, respectively. The latter was detected by using the unloading elastic compliance method. Some attempts to improve the accuracy of measurements with the aid of soft-ware of computer programs are described.
