چکیده انگلیسی

In this study, an experimental analysis for determining the fatigue strength of HDPE-100 under cyclic loading is presented. The curve of cumulative fatigue damage versus number of cycles (D-N) was deduced from stiffness degradation. Based on the three stage damage trend, the remaining fatigue life is numerically predicted by considering a double term power damage accumulation model. This model is found to be accurate, both in modeling the rapid damage growth in the early life and near the end of the fatigue life. Numerical results illustrate that the proposed model is capable of accurately fitting several different sets of experimental data.
