Linear polystyrenes, rheological properties

The Finite Difference Method was employed to solve the coupled and non-linear partial differential equations. Prior to the simidation, temperature-dependent material properties and physical constants of the polystyrene-C02 system were collected [11-19]. At the initial expansion stage, the diffusion equation was first resolved. Then the mass change of blowing agent inside the cell was determined. Subsequently, the viscoelastic term was calculated by solving for the stress conponents based on the rheology equation. As a result, the cell size at the next time step could be understood. Time evolution would not cease until the cells got close to each other. During the... [Pg.2957]
