| Abstract | ||
| Stress concentration is critically looked at in view of the large number of reported cases of failure attributed to the presence of some form of stress concentration; these are usually associated with stress concentration. This paper studies the effect of both notch angle and notch root radius on notch sensitivity index of medium carbon steel .Bending fatigue tests carried out on specimens carrying angular notch. Results showed that the notch angle and notch root radius the increment of is accompanied by a corresponding increase in endurance and tensile strength. On the after hand stress concentration effect is found to decrease. Notch sensitivity variation with both stress concentration factor Kt and fatigue strength reduction factor Kf is found similar. | ||
