DEVELOPMENT OF 2D THERMAL ELASTO-PLASTIC FEM SIMULATION SYSTEM

Abstract

Abstract: A 2-D thereto-mechanically-coupled elasto-plastic FEM software is developed, which is based on ANSYS program. Using the finite strain theory and the fully coupled method, this system can be used to analyze the whole process of 2-D metal forming problem. The system has been verified by comparing with the measured results of temperature in a compress test and by simulating a cylinder backward-extrusion. The computer simulation results are in good agreement with the experiment results.

Key words: ANSYS program, Finite strain theory, Metal forming, Thermal elasto-plastic FEM, Thermo-mechanically coupled
