Abstract
It was impossible to get standard specimen due to sampling condition. Then nonstandard small specimen should be designed to test performance of the material. The small specimen was designed to test S-N curve in high frequency fatigue test machine PLG-100C. After discussing two problems of the experiment,the key results were as followed: specimen with small section size which was not accorded with GB/T 3075-1982 could be tested in high frequency fatigue test machine PLG-100C effectively;the transition clamping designed meet the test request of small specimen in high frequency fatigue test machine PLG-100C.
