i A method for determining material’s equivalent stress-strain curve with any axisymmetric notched tensile specimens without Bridgman correction Shengwen Tu 1 , Xiaobo Ren 2 , Jianying He 1 , Zhiliang Zhang 1 1 Department of Structural Engineering, Norwegian University of Science and Technology, Trondheim 7491, Norway 2 SINTEF Materials and Chemistry, Trondheim 7456, Norway Highlights A correction function is proposed to determine material’s equivalent stress-strain curve with any axisymmetric notched tensile specimens. No Bridgman correction is needed. The proposed correction function can be applied to perfectly plastic materials. The proposed correction function can be used to measure the equivalent stress-strain curve of each individual material zone in a weldment.
