概要:

A method for the determination of dynamic stress-strain relation of materials by means of instrumented Charpy impact testing technique was proposed and its validity was shown by some measured examples. The dynamic strengths of steels (S55C, SCM3, SUJ2, SK3) hardened from HV340 to HV850 by heat treatment were obtained from stress-strain relations measured by the present method. As a result, it was found that the yield strength of hard steels increases roughly … linearly with increasing hardness and that under dynamic loading was 20∼30% higher than that under static one. Those strengths are also found to become maximum in the vicinity of HV700. 続きを見る
