Serviceability criteria - no deformation criteria in the client UDS - how to interpret deformations

thread794-492743

Hi,

In continuation of the thread mentioned here, I have a question. When we are evaluating the deformations in an elastic plastic analysis, what value of deformations do we say we are allowed to go upto if nothing is specified by the user of the vessel? I know that the deformations should not be large enough to render the equipment non functional or not functioning as intended but not sure how to satisfy this criteria.

Any light on the matter or any other interpretation if we do not know the limit of deformations in UDS?

Thanks,
Shiraz

The criteria, if not specified by in the UDS, is a matter of engineering judgement. There is no Interpretation on this matter, nor is it likely that one will be issued.
