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.
