Glass Sheet Stress Profile Measurement (101)
Problem: Internal stress profiles in glass sheet govern glass strength, but no method existed for measuring these stresses
Project Activity Scope (from Technical Overview Chart): Interaction Mechanisms through Measurement & Analysis Method Development
PNNL Solution:
- Developed unique optical method for measuring stress profiles
- Established a laboratory-scale measurement system
- Performed experiments that validate measurement principle
- Continued efforts to develop an instrument for routine use
Capabilities Employed to Meet Client Needs: Optical physics including polarization effects and thermally created refractive index gradients; laser interactions with materials; optical system design; laboratory instrumentation development; modeling of optical interactions; test planning, performance, and reporting.
