Advanced Glass Science Course

Advanced 3-Day Course on Ceramic and Glass Manufacturing with China Glass Ceramic Inc.

This short course is a follow-up on to the basic glass-to-metal sealing short course presented at China Glass Ceramic Inc. . It is intended for practicing engineers and advanced technicians. This course goes into detail on the chemistry, crystallography, mechanical properties, and finite element analysis of glass to metal seals.

Participants will use finite element analysis to model actual glass-to-metal seals. Participants will then fabricate the seals modeled and compare actual results to those predicted by the model.

Participants are required to bring a laptop computer equipped with Windows 7 or 8 and Microsoft Excel^®, or equivalent spreadsheet program. (A Windows machine is preferred as difficulty has resulted in running the FEA program on Apple machines running a Windows simulator.)

Participants are encouraged to bring specific seal designs, and problems of interest for discussion and possible analysis.
