METHOD FOR DETERMINING THE CRACK RESISTANCE OF METALLIC MATERIAL |
| 摘要 |
The proposed method for determining the crack resistance of metallic material consists in loading the material sample by a static force until a crack is produced and determining the ratio between the crack length and the sample width. To ensure the absence of tangential stresses in the sample that are perpendicular to the longitudinal axis of the crack, the said ratio must be 0.40 à 0.42.
