THERMALLY INDUCED RESIDUAL STRESSES IN INJECTION MOLDING OF PLASTIC COMPONENTS.

The paper describes the evaluation of nonlinear thermally induced residual stresses in injection molding of plastic components. The computational methodology adopted is based on the transfinite element approach which is a hybrid scheme as it combines transform methods and classical Galerkin schemes with finite element formulations to preserve the modeling versality. The applicability of the proposed formulations for understanding the physics and nature of the nonlinear thermally induced stresses in injection molding of plastic components demonstrates the capabilities and potential of the methodology. Results obtained agree qualitatively with earlier research studies and experimental findings.
