Quantitative analysis of three dimensional images of dimple and stretch zone

ディンプルとストレッチゾーンの3次元画像定量解析
The fracture surface reconstruction technique has been applied to dimple and stretch zone patterns to elucidate the quantitative relationship between three-dimensional parameters of fracture surfaces and material properties. The followings have been made clear. Testing temperature of Charpy impact tests is closely related to the averaged ratio of surface area and the averaged depth of dimples irrespective of kinds of steels; the higher the former, the greater the latter in dimple fracture

... es. Similarly, the greater the absorbed energy is, the greater the averaged ratio of surface area and the averaged depth of dimples become. When the height of stretch zone is high, the height can be automatically and precisely deduced without human assistance.
