Plastic n-factor for three-point bend specimens: Analysis of instrumented Charpy impact test results for AISI 308 weld and AISI 316 stainless steels
作者： PR Sreenivasan , SL Mannan
关键词:
摘要: In this paper, instrumented impact test results obtained using V-notch and precracked Charpy specimens of AISI 308 weld and AISI 316 stainless steels are analysed for determining the plastic η-factor for three-point bend specimens used in J-integral evaluation. Tested 316 stainless steel specimens were in various thermal aging/cold-work conditions whereas 308 weld specimens were in the as-welded condition. The results are analysed using the various procedures proposed in the literature and compared with experimental …
