高强钢厚壁管失效评定图技术研究

Research of the failure assessment diagram technology of thick-walled high strength steel tubings

按英国ＣＥＧＢＲ６第３版选择２的方法制定高强钢厚壁管失效评定图（ＦＡＤ）。根据测试材料断裂韧性试样的有限元计算和实验所获得的选择３ＦＡＤ初步验证选择２ＦＡＤ的有效性。

The failure assessment diagram of the thickwalled high strength steel tubings was drawn based on the Option 2 Method,the 3rd edition,CEBE.The Option 2 FAD was considered efficient through the finite element analysis of the samples of fracture toughness of the tested materials and the Option 3 derived from experiments.
