Springback Prediction

Abstract Springback phenomenon is well predicted for some mild steel materials, but not for steels with higher strength. One of the most used tools to stamping optimization is usage of finite element analysis. In order to accurate describe the real behaviour of the materials for stamping of vehicle panels, the application of proper hardening rule seems to be crucial. Due to higher accuracy of predicted results, high strength steel sheets are usually modelled by means of kinematic or mixed isotropic-kinematic hardening models. In this paper the springback prediction of advanced high strength steel DP600 by numerical simulation was investigated. Through cyclic tension-compression tests, the material characterization has been performed for DP600 steel sheet. Different hardening models (isotropic, kinematic and mixed isotropic-kinematic) used in the simulations were compared with expreriment. The Yoshida–Uemori model succesfully describe the kinematic behaviour of the material and provided more accurate results than others.

Based on the experimental study of shear strengthened of reinforced concrete rectangular beam strengthened by high-strength steel wire mesh and polymer mortar , the finite element extended analysis was used. The finite element analysis software showed that with the increasing of the strand dosage and reinforcement strand length,the shear strength and stiffness of strengthened members improved . However,with the increasing of shear span ratio , the shear strength and stiffness reduced obviously .
