The prediction of the force - displacement relation by the finite element method (FEM) is very important for the design of terminals in connectors. For simulation, an accurate model of stress-strain (s-s) responses of the materials is required. When the materials are deformed in the forward and then the reverse directions, almost all spring materials show different s-s responses between the two directions, due to the Bauschinger effect. This phenomenon makes simulation difficult because the s-s response depends on the prior deformation of the material. In this paper, the authors report s-s- response of Cu-Ni-Si copper alloy, which is widely applied to terminals of automobile application, by tension and compression testing. Its mathematical description with Yoshida-Uemori model, which is a constitutive model having high capability of describing the elastic and plastic behavior of cyclic deformation, have been also reported. The calculated s-s responses were in good agreement with the corresponding experimental results. Therefore, the use of this model for FE simulation would be recommended for a more accurate prediction of force-displacement relation of the spring. |
