3D Rigid-Plastic Finite Element Analysis for Skew Rolling Process of the Stepped Part被引量：2
《Journal of Materials Science & Technology》2003年第z1期38-40,共3页Gang FANG Pan ZENG 
The research is supported by the National Natural Science Foundation of China ((No. 50205013 and No. 50175060). Special thanks are expressed to the Mr. Guoji Li from Science Forming Technology Corp. (SFTC) for his assistance and advice on the simulation work of.this paper.
Based on rigid-plastic finite element method, a skew rolling process of stepped part is simulated. Considering nodesaving and effective remeshing, the tetrahedron solid elements are used to discrete workpiece. The wor...
