Influence of carbon on hardness and strength of steels ...
Shore Hardness is nothing but a measure of the hardness of a given material or how resistant it will be to permanent indentation. It is measured by the depth of indentation that is created on the material with a specified force. The measuring instrument is actually a durometer, but Shore Hardness is named after its inventor Albert Shore.

Shore Hardness Durometers - PosiTest SHD | DeFelsko
Hardness is a measure of the resistance to localized plastic deformation induced by either mechanical indentation or abrasion.Some materials (e.g. metals) are harder than others (e.g. plastics, wood).Macroscopic hardness is generally characterized by strong intermolecular bonds, but the behavior of solid materials under force is complex; therefore, there are different measurements of hardness ...

Shore A scale is the most widely used scale for the roller industry. Durometer hardness can be an instantaneous reading or set to be taken up to 15 seconds after load is applied. The second method used to measure hardness is the Pusey & Jones Plastometer instrument, which is mainly for the paper industry and referred to as P & J hardness.

Rockwell Hardness - an overview | ScienceDirect Topics
The hardness of steel is important to many processes. Steel hardness describes the properties of steel that enable it to resist plastic deformation, indentation, penetration, and scratching. In engineering, steel hardness is important because the inherent resistance of the surface to withstand friction or erosion by oil, steam, and water, typically increases with the relative hardness of steel.

Durometer Shore Hardness Scale - Smooth-On, Inc.
The Rockwell scale is a hardness scale based on indentation hardness of a material. The Rockwell test measuring the depth of penetration of an indenter under a large load (major load) compared to the penetration made by a preload (minor load). There are different scales, denoted by a single letter, that use different loads or indenters.
