متن کاملInfluence of Residual Stress on Fatigue Life of Hot Forged and Shot Blasted Steel Components
Hot forging is a common manufacturing process for the production of large quantities of engineering components. Residual stresses are developed in forged components as a result of various aspects of the manufacturing process, including subsequent cooling, and heat treatment. Residual stresses can significantly affect the deformation and fatigue failure of materials. Hot forged EN15R steel bars ...
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 کاملEffect 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 کاملStress Concentrations , Fatigue , Fracture
The fundamental topic in this document is the development of cracks in steel. For structures subjected to cyclic loads, such cracks can develop over time and ultimately reach the size at which some dramatic failure occur. While this problem is rare in structures made of “mild steel,” the use of “high tensile” steel changes that situation. It is straightforward to double the strength of mild ste...
