Abstract
The influence of the flow history experienced duringinjection molding on the mechanical propertiesof amorphous polymers is investigated. It is demonstratedthat flow-induced molecular orientation onlycauses a small anisotropic effect on the yield stress,which can be regarded as insignificant with respectto its absolute value. Its influence on the post-yieldstrain-hardening response is also shown to be imperceptible,in contrast to a orientation which is appliedduring deformation below the glas transition.
