The ductile failure has been of importance in many engineering branches. It is related to extensive plastic deformations under static loading, while the effect of strain rate and temperature can be easily incorporated. The testing on bulk material has been significantly developed recently, whereas the miniature testing has been still under investigation. The small scale experiments are important in many applications, such as the power industry generally. It is namely related to the piping when the vintage material has to be examined or nuclear industry for a shortage of an irradiated material available. The present paper focuses on the calibration of phenomenological ductile fracture criteria - with and without Lode dependency - for AISI 316L. The whole model is then applied to the small punch testing to reveal the predictability. The differences are accounted for in a quantitative as well as qualitative way.
