An Estimation of Ramberg-Osgood Constants for Materials

Jan 01, 2019 · Relatively ductile materials undergo significant cross-sectional reduction due to necking of material after ultimate tensile strength (stress at point of zero slope in ï ³-ï ¥ curve). Hence, to study ductile materials behavior, true stress-true strain curves are often utilized. _____ *Corresponding author.
