SEM-based In-situ Fracture Measurements of Ceramics and Metals: Richard Vinci1; 1Lehigh University
    Fracture experiments performed at the micrometer scale within an SEM environment offer the opportunity to examine failures of specific features such as individual interfaces. They also make it possible to examine materials such as thin films that are difficult to probe using conventional macroscale techniques. However, issues such as plastic zone size and fracture mode must be taken into account in order to correctly interpret the measurement results. Several methods for performing in-situ tension and bending fracture tests will be reviewed, and examples will be presented representing brittle ceramics, ductile metals, and nanocrystalline metals that range in behavior from brittle to ductile.
