| Abstract: | This paper discussed measurement uncertainty in metallic materials-charpy notch(V-notch) impact testing at room temperature.The measurement uncertainty affecting impact testing results of metallic materials were evaluated in detail.The authors discussed the uncertainty sources from five aspects such as the shape and size of the sample,the smooth degree of the bottom of the notch,the machine for impact testing,the testing temperature and discriminable scale of the measure for examining the size of the sample.Calculation,composing and evaluation of the uncertainty were also mentioned. |
| Keywords: | Charpy notch Measurement uncertainty Impact testing Probability Distribution |
