Microhardness indentation application and limitation in fracture-toughness evaluation of ceramics
The use of a microhardness indentation as a controlled flaw in a flexural specimen for measuring fracture toughness in advanced ceramics is critically evaluated. From a review of fracture-toughness testing met...
