| Abstract: | The strain fatigue behavior of polymer Acrylonitrile-Butadiene-Styrene （ABS） sample with notch under asymmetrical cyclic loading are studied, and the strain fatigue formula and the △ε-Nf diagram are fitted in this paper. The results show that the strain fatigue notch factor of polymer ABS is not related to the arc radius of notch bottom. |

| Keywords: | polymer strain fatigue formula △ε-Nf curve strain fatigue notch factor |
