The purpose of this thesis is to study the fatigue limit when the constant stress is appiled to both notched and unnotched specimens, and investigate the effects to the constant stress level when the two level stress is applied to the same specimens at the 250℃. The specimen used for this test js SM₄5C, mechanical structural steel annealed. Also experimental results is compared with the damage values obtained by theoretical Miner's rule.
