Stress-Strain Behaviour of 316L Stainless Steel under Proportional LoadingJakub Sagáčik
STRESS STRAIN CURVESTRAIN HARDENINGIn this study, the commonly used well known empirical relationships between stress and strain are analysed with respect to experimental stress-strain curves obtained for 316L austenitic stainless steel. It was observed that the Ludwick and Ludwigson equation fits the ...

Daniel Montañés - Cañuelas, Buenos Aires, Argentina January 3, 2023 A.Hi Girius, Springback is a result of material properties, specifically the elastic region of the stress strain relationship (curve). You "may" be able to reduce the springiness of the rings by heat treating them, bu...
Looking at the shape of the developed stress-strain curves, what can one tell to help explain a large deviation in modulus? Yield and Ultimate strengths are within spec. Chemistry and Hardness are nominal. Replies continue below Recommended for you 3DEO Launches 316L Stainless Steel The imp...
Fig. 5. Comparison of stress-strain curve for the untreated and UNSM-treated specimens obtained by 3-point bending tests. The nanoindentation tests were performed on the untreated and UNSM-treated specimens in order to investigate the effects of nanocrystalline surface layer and grain refinement on...
