Investigation of R-Curve Behavior in Glass Ceramic Materials
- Sandia National Lab. (SNL-NM), Albuquerque, NM (United States)
We demonstrate the ability to measure R-curves of brittle materials using a method adapted from Theo Fett et al. The method is validated with a NIST standard reference material and demonstrated using Si3N4 of two different microstructures; glass-ceramic, and PZT. As expected, each material's R-curve is seen to be slightly different with glass-ceramics showing the most pronounced R-curve effects. Plans for future applications and experimental efforts are discussed.
