Relationship between Hardness and Elastic modulus? iMechanica

The Rockwell scale is a hardness scale based on indentation hardness of a material. The Rockwell test measures 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. The result is a dimensionless number noted as HR… http://www.plasco-corp.com/plasco/html/tech_topics/materials_archive/hardness.mat_archive.html d\u0026d objects

Shore Durometer Hardness Testing of Rubber and Plastics

Webof Plastics.4 The Shore Durometer hardness test was conducted, as it does not limit the sample thickness to 6 mm minimum, a requirement of the often-used Rockwell Hardness test. The Shore Durometer hardness test requires the testing location to be 12.0 mm from each edge. For this WebRockwell Hardness Testing of Plastics The hardness testing of plastics is most often measured by the Rockwell hardness test or Shore (durometer) hardness test. Both methods measure the resistance of the plastic toward indentation, thereby providing an empirical hardness value.
