¿ä¾à2 Fatigue tests are conducted for design and(or) maintenance. For fatigue strength evaluation, accurate S-N relationship is firstly determined for metallic materials used. However, many researchers are facing difficulties in deciding a series of test loads, stress level number, stress range intervals, etc. In this study, the rational algorithm and software to conduct fatigue tests was developed. For achieving this purpose, a diversity of methods of fatigue strength estimation were studied. The fatigue software automatically presents real fatigue test results. Finally, practical use of this algorithm and software was proved through verification test.
