In this paper are presented experimental analyses of the behaviour of 316L stainless steel in regard to fracture, according to standard methods of investigation on modified tensile C(T) specimens. The S316L alloy is selected for this experimental analysis, often used in many engineering applications. This alloy is not prone to corrosion as other austenitic steels with a higher share of carbon. Results show that material behaviour, in terms of dependence of stress intensity factor (SIF) value relative to thickness of the plate, is necessary to assume with a different model when the specimen thickness is very small. Application of standards in the field of investigation of material resistance to fracture allow simultaneous determination and connection of several fracture mechanics parameters.
