In Part I of this study a coupled thermo-mechanical finite element model for the simulation of the entire precision glass lens molding process was presented. That study addressed the material definitions for the molding glass, L-BAL35, computational

Coupled thermomechanical finite element models were developed in ABAQUS to simulate the precision glass lens molding process, including the stages of heating, soaking, pressing, cooling and release. The aim of the models was the prediction of the dev

In this paper, we report the development of a kinetic model for precisely predicting glass material property response to a defined molding profile. The glass viscosity, thermal expansion, and specific heat properties for two commercial optical glasse

The viscosity behavior of (1 − x )NaPO 3 − x Na 2 B 4 O 7 glasses ( x = 0.05–0.20) have been measured as a function of temperature using beam-bending and parallel-plate viscometry. The viscosity was found to shift to higher temperatures with in

We present the development of a model used to predict final geometry of molded lenses using glass viscosity data, friction data determined from ring compression tests, and structural relaxation data from differential scanning calorimetry tests.
