Proposed Testing to Assess the Accuracy of Glass-To-Metal Seal Stress Analyses.

摘要

The material characterization tests conducted on 304L VAR stainless steel and Schott 8061 glass have provided higher fidelity data for calibration of material models used in Glass-To-Metal (GTM) seal analyses. Specifically, a Thermo-Multi-Linear Elastic Plastic (thermo-MLEP) material model has been defined for SS304L and the Simplified Potential Energy Clock nonlinear viscoelastic model has been calibrated for the S8061 glass. To assess the accuracy of finite element stress analyses of GTM seals, a suite of tests are proposed to provide data for comparison to model predictions
