THERMOMECHANICAL MODELING OF SOLIDIFICATION PROCESS OF SQUEEZE CASTING II. Numerical Simulation and Experimental Validation

Based on the thermomechanical model and solution methodology described in Part I, a finite element program for simulating the solidification process of squeeze casting was developed. By using the program and a constitutive relationship based on Gleeble test data, the solidification processes of A356 aluminum alloy under different process parameters were simulated. Squeeze casting experiments were carried out for validating the developed model and program. It is shown that the results of numerical simulation are in good agreement with the experimental results.
