Numerical Simulation Of The Temperature Field And The Residual Thermal Stress Field In The Cooling Process Of The Molded Polymer Parts

With the development of the theories of the rheology, heat transfer, thermal stress, computer graphics and the modern optimization, many physical circumstances and complex boundary conditions in the molding process, such as the temperature dependent of the physical properties of the polymers, were solved by Numerical solution. Heat transfer, thermal stress and the stress distribution in the parts could be simulated.This paper constructed the physics model and the mathematical model of the temperature field and the residual thermal stresses field in the cooling process of the molded polymer parts, based on the he material science, theory of heat transfer, rheology, computer graphics, exploited the finite difference method to numerically simulate the temperature field and the residual thermal stresses field in the molded part. The cooling processes of the polymer moldings were numerically simulated by dynamical quantitative and microscopic methods. This paper provided the...
