Effect of Mean Stress on Low-Cycle Fatigue Strength of a Medium Carbon Steel S45C - True Stress-Controlled Cycling- by
Effect of Mean Stress on Low-Cycle Fatigue Strength of a Medium Carbon Steel S45C True Stress-Controlled Cyclingby Tatsuo ENDO*, Shoji HARADA*, Yoshihiro FUKUSHIMA* and Haruo SAKAMOTO** Nominal stress-controlled low-cycle fatigue life under imposed mean stress is affected by elongation or contraction due to cyclic stress-induced creep. Therefore, the effect of mean stress was examined by a micr...
متن کاملA Stress Analysis of Bending Fatigue Specimens Using the Finite Element Method
A numerical analysis of stresses generated in bending fatigue specimens has been performed employing the commercially available FEM-program ADINA. The results show that transverse bending occurs, giving rise to a stress enhancement in the edge region. A stress maximum is obtained approximately 2 mm away from the specimen edge. This result is consistent with the fact that fatigue initiation pred...
متن کاملNumerical and Experimental Evaluation of Residual Stress and Fatigue Strength of Steel CK35 in Shot Peening Process
In shot peening process the work piece surface is struck by a large number of balls and compressive residual stress is generated on the surface. So, mechanical properties such as fatigue strength, stress corrosion resistance, smooth shape and ... will improve. In this paper, the balls with a speed of 100 to 200 m/s were struck on the steel samples and fatigue strength compared with specimens wi...
متن کاملBending Fatigue Failures in Valve Steel
In the present paper the effect of defects (viz. pits, gouges and oxide inclusions) will be reported. Although certain defects were uniformly distributed over the specimen surface, the majority of all fractures started in the edge region. An explanation to this behaviour is presented in terms of stress enhancement in the edge regions due to edge deflections.
