摘要

本文提出了一个以有限元法为基础的光学玻璃退火应力计算模型。可以在微机上预测一定退火规程和工艺条件所确定的暂时应力和退火后的永久应力。最后按三维应力状态计算第二类光学均匀性和应力双折射。

Abstract

In this paper a mathematical model based on finite element method for calculating stresses in optical glass during its annealing under various technical conditions with microcomputer is introduced. Finally

the inhomogenity of refractive index and birefringece caused by the stress are calculated according to stress states of optical glass in three dimensions
