Effects of Notch Radius on Brittle Fracture of Mild Steel in Slow Tension Test

Comparison of the Results of Slow and Impact Tension Tests

Abstract

Using the same steels as in the previous report on the impact tension test of mild steel, we performed slow tension tests of round bars with circumferential notch, and studied the effects of notch radius etc. on the brittle fracture of mild steel.
The validity of the theoretical relation between the transition temperature and notch radius which were based on the theory proposed in the previous paper was verified by the experimental results as in the impact tension test.
