 note = {application/pdf, The result obtained by this test on S 35 C steel，annealed，is summarized as follows :(Regardless of the kind of the cycled stress，both torsional and bending stress which had the same life in the respective constant stress fatigue test，are called of the same magnitude for the present).　　　1)　When the 2ary stress was smaller than the 1ary， the accumulated cycle ratio Σn/N＜1 at the life； and when larger， Σn/N＞1. For the 2ary stresses of the same magnitude，Σn/N  became larger when the 1ary stress was of another kind than the 2ary.　　　2)　During the 2ary cycle， the hardness of the tested material increased when the 2ary and 1ary stresses were of the same magnitude， and decreased when the 2ary one was either larger or smaller than the 1ary one. 　　　3)　After about the cycle whenΣn/N＝0.5，the plastic strain width ?ε_p value was higher for the higher stress amplitude. Before this cycle， there was no such relation.　　　4)　It is considered that the maximum shearing stress induced during the cyclic test exerts governing influence overΣn/N value at the life，hardness and ?ε_p.},
