Abstract
The residual stress formation mechanisms are studied for injection mold process. A simple, but physically relevant, elastic solid model is assumed (viscous melt and purely elastic solid). Residual stresses found in the constrained quenching case are proportional to the maximum melt pressure and are tensile near the surfaces. A comparison between this model and Baaijens's model is made.
