Cracking study using scratch testing |
Cracking can be studied using either instrumented indentation or scratch testing depending on the applications.
Cracking can of course be observed visually after an indentation test is completed in order to compute the fracture toughness, but in some cases, the indentation curve will also show the exact load at which cracking occurred.
