Shot Peening of a Titanium Alloy for Medical Implant Applications with Ziirconia Shot
Shot peening with steel shot followed by a cleaning process with glass beads is commonly used as surface finish in the production of modular hip endoprostheses. The induced compressive residual stresses increase the resistance against fatigue and fretting fatigue. The surface roughness can be adjusted in a range that enhances the physiological acceptance I compatibility of monolithic ~rnplants....
متن کاملSide Effects of Shot Peening on Fatigue Crack Initiation Life
Shot peening beneficial effects on fatigue life of mechanical components are well known. However, there are some reports in the literature that indicate inappropriate shot peening parameters tend to reduce the fatigue life. It is therefore, the purpose of this study to find a logical quantitative justification for these observations. Using finite element method, a dynamic elastic-plastic simula...
متن کاملEvaluation of Fatigue Strength Improvement by CFRP Laminates and Shot Peening onto the Tension Flanges Joining Corrugated Steel Webs
Corrugated steel web with inherent high out-of-plane stiffness has a promising application in configuring large span highway bridge girders. Due to the irregularity of the configuration details, the local stress concentration poses a major fatigue problem for the welded flange plates of high strength low alloy structural steels. In this work, the methods of applying CFRP laminate and shot peeni...
متن کاملManual shot peening intensity and coverage effects on fatigue performance of aluminum alloy
Shot peening has been developed to enhance the fatigue strength of metallic parts. However, improper shot peening can decrease the fatigue life due to induced high surface roughness and residual tensile stress. The effectiveness of the manual shot peening process is accomplished by the control of the process parameters to provide a uniform intensity and coverage throughout the work piece. This ...
متن کاملEffect of Shot Peening on the Fatigue Behaviour of Cast Magnesium A 8
Shot peening is known to improve the fatigue performance of structural metallic materials. The improvement in fatigue life is derived primarily from compressive residual stresses that are introduced into the near-surface of the components and which hinder crack initiation and growth. Magnesium alloys are finding increasing use in automotive applications, but their relatively low strength means ...
