Fundamentally, hardness testing determines the resistance a material exhibits in response to the permanent deformation of another material’s penetration. If I take a piece of metal and rub something ...

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 ...

ALTHOUGH the hardness of a substance is not a physical constant, and cannot be expressed as a function of known physical constants, the idea of hardness is a familiar one, and empirical determinations ...

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.
