✦ Synopsis

Low cycle fatigue tests were carried out by the authors using a number of fatigue specimens of LY12CZ aluminum alloys, annealed 40CrNiMoA alloy steels and BHW35 pressure vessel steels which are of monotonic cyclic hardening or softening property, respectively. The concept of cyclic hardening or softening factor was proposed and the quantitative description was made with respect to the cyclic hardening or softening process. The stress--strain relation model of its process was presented. The test results are in agreement with the above model.

Low-cycle fatigue crack propagation has been modeled successfully by an equation employing the cyclic J-integral, A/. The use of this equation in practice is hindered by the difficulty of calculating AJ. A load-deflection hysteresis diagram must be obtained to estimate its value for several points o
