Discussions related to the analysis method for perforation reinforcement
Thread Content
Regarding the analysis method for hole reinforcement in the conventional design standard GB150.3, clause 6.6.1 specifies in its scope of application that for the materials of cylinders, nozzles, or reinforcement elements, the ratio Rel/Rm of their standard yield strength at room temperature to the lower limit of their standard tensile strength must be ≤ 0.8. So the question is: please list the materials for which Rel/Rm > 0.8
Huh, no one is supporting my view; then I’ll support it myself. For quenched and tempered steel plates per GB19189, since Rel/Rm > 0.8, the analysis method for reinforcement through drilling holes does not apply. But then again, it seems I’ve never seen ordinary containers made of quenched and tempered steel sheets… I’m not sure what the standard means
