Three‐dimensional finite element simulation of connecting rod forging using a new remeshing scheme

Abstract

The design of the hot precision forging of complicated shapes demands a systematic simulation of the process in order to control the material flow and the temperature distribution properly. The finite element method (FEM) has been extensively and effectively applied to the numerical simulation of forging processes [1][2][3][4].Most three-dimensional forging parts, however, involve complicated geometry and flow characteristics during forging. Especially, due to the complexity of deformation and mesh degeneracy, the finite element mesh needs to be regenerated many times during the analysis. Thus, the design of meshes in initial billets as well as in intermediate remeshing stages plays an important
