Time Dependency of Stress/Strain on 304 SST
Time Dependency of Stress/Strain on 304 SST
(OP)
I'm looking for information on the effect of very rapid stress onset on 304 SST. We have a pressure vessel which was subjected to an internal explosion and I'd like find out if we can use the lack of deformation of the vessel as proof that the vessel was not overpressurized. Essentially I'd like to make sure that the material couldn't approach UTS without getting some yielding. The overall time scale for the stress peak was probably a few milliseconds.

There are a lot of material and environmental parameters that affect fracture behavior.
E. g., were the welds annealed, was the contained solution something that might cause embrittlement or intergranular corrosion. What was T & P and for how long? A very major question is where did the failure originate? Along some seam? Surface analysis of the initial fracture surface might be invaluable.
mcguire,
Wouldn’t less martensite mean more plastic deformation?
