title = "Numerical simulation prediction of gas trapping in aspheric lens molding based on Coupled Eulerian-Lagrangian method",
abstract = "Numerical simulation of glass molding and research on material viscoelastic have become increasingly important with the deepening of glass molding research for optical devices. In this study, we developed an accurate and efficient numerical simulation method for the glass aspherical lens molding process. According to the FEM simulation results of aspheric lens molding, gas trapping occurred in the molding of preforms of size 5 mm, which was consistent with the experimental results. The molded lens was tested by profilometer and a gas trapping area of about 3 microns deep and hundreds of microns wide existed at the top of the lens, which was also consistent with the FEM analysis results. The consistency of the FEM predicted results with the experimental results illustrated that the Coupled Eulerian-Lagrangian (CEL) method can be used for the prediction of the gas trapping phenomenon in aspheric lens molding.",
