Notes:
The processing of thermoplastics often requires conversion of a solid to a viscous fluid under shear conditions. In this study, solid blocks of polystyrene were softened on a hot, moving surface over a range of surface temperatures and velocities. The conservation equations for mass, momentum, and energy were applied to the fluid layer and simplified by an order of magnitude analysis. An integral method of solution was developed which predicted rates of softening that agreed closely with the measured rates.
