A material’s hardness relates to its mechanical resistance when subjected to mechanical indentation by another harder body. Diamond is considered the hardest natural material and is typically used for ...

Hardness Testing provides a thorough overview of the most common hardness testing methods, including Rockwell, Brinell, Vickers, Knoop, rebound, and ultrasonic tests. This class presents a description ...

This film discusses hardness testing methods in engineering, specifically focusing on the Brunell and Rockwell hardness tests. It explains how hardness is measured through indentation and penetration ...

Sheet metal forming operations can vary greatly in their processes. From simple bending to stretching to deep drawing of complex parts, sheet metal forming operations may take many forms. Image Credit ...

Nanoindentation of metallic samples is closely related to hardness testing methods such as Vickers. The Vickers hardness test requires an imaging method to determine the size of the indentation cup.

This class presents a description of each hardness testing method, along with discussions on how to choose and perform a test, how to read hardness ratings, and how to prevent common errors. Hardness ...
