Numerical Simulation of Casting Thermal Stress Using Finite Element Method Based on MATLAB Platform

By using of finite element method(FEM),an accurate simulation of 3D casting thermal stress has been proposed.Based on the MATLAB platform and FEM,a simulation program of casting thermal stress was developed.In order to validate the algorithm and program,a typical specimen of stress frame was used.By comparison with the simulation results of commercialized software ANSYS,the results of this study indicate that the presented algorithm and program can be used to well predicate the casting deformation and the thermal stress concentration.
