WRONG YIELD STRESS AT 50C ON VVD
WRONG YIELD STRESS AT 50C ON VVD
(OP)
Hı ,
I have a question abouth vvd ( vissual vessel design ) program.
For exapmle when i choose AD2000 for design standart and T max :50C material P355GH . VVD calculating with 355 mpa yield stress .As you know acc to 10028 yield stres at 50C for P355 gh is 343 mpa not 355 !!!... why is it calculating like that ?
When i enter 51C it is fixing , yield stress is being 342.6 mpa but for 50C it is calculating with 355mpa ...
For this reason i m entering 51 C on vvd when i need a calc for max working at 50 C .
İs it a kind of bug of this program or is that any point that im missing ? ..

But AD2000-W1:2006 subclause 6.7: The values indicated in material specifications ...for 20°C are valid up to 50° C, the values indicated for 100°c are valid up to 120°C...
