DIN EN ISO 11782-2-2008 金属和合金的腐蚀.腐蚀疲劳试验.第2部分:使用预开裂样品的裂纹扩展测试
Corrosion of metals and alloys - Corrosion fatigue testing - Part 2: Crack propagation testing using precracked specimens (ISO 11782-2:1998); German version EN ISO 11782-2:2008
1.1 This part of ISO 11782 describes the fracture mechanics method of determining the crack growth rates of pre-
existing cracks under cyclic loading in a controlled environment and the measurement of the threshold stress
intensity factor range for crack growth below which the rate of crack advance falls below some defined limit agreed
between parties.
1.2 This part of ISO 11782 provides guidance and instruction on corrosion fatigue testing of metals and alloys in
aqueous or gaseous environments.
