Hey everyone, had a question regarding MDMT. If I am understanding the Code correctly, MDMT is a value the vessel can operate at and still have a high toughness so that the material is in a ductile region when it is failed. Is that right?
That being said if I operate below MDMT, theoretically is the vessel still able to operate and pass all the other Code requirements, but now if my vessel fails I will fail in a brittle manner (not leak before break)? Is this right?
Finally, when calculating leak before break on thicker vessels with an assumed flaw, does this calculation really care about MDMT? Can you have a leak before break condition with a vessel that is operating below it's MDMT?
