Abstract
A new method is employed to directly predict the development of yield stressdistributions in injection molded products of glassy polymers. The approach isbased on the results of a study on the temperature dependence of theevolution of yield stress during annealing of polycarbonate below Tg. Incombination with the process-related thermal history, derived from numericalsimulations of the injection molding process, an estimate of the yield stressdistribution throughout a product can be obtained. Computed yield stresses ofinjection molded plates prove to be in excellent agreement with theexperimental values, including their dependence on mold temperature andplate thickness.
