Stress-strain Curve Correction Based on Finite Element Method

Abstract Necking is a very common phenomenon in uniaxial tensile experiments. It particularly prominent materials with high-stress levels. can be considered deformation destabilization or localized concentration of deformation. The occurrence this lead to the failure stress-strain curve material. Therefore, paper will examine problem correction tension for high levels yield stress. Due class materials, material quickly undergoes necking after entering yield, resulting distorted curves. Sometimes, there not even enough information fit intrinsic parameters. In paper, real mechanical response such inverted according finite element method correct
