Unique portable device for the performance of standardized, static ball penetration tests according to Brinell up to a max. load of 29420 N. It is possible to carry out hardness tests on materials and ...

Rockwell hardness testing is a method of determining the relative hardness of a material. In this test, hardness is measured by determining the depth of residual penetration by a steel ball or a ...

When designing metal parts, it's important to specify their hardness. However, many engineers have only a shaky understanding of what hardness actually is, or how it's measured. There are good reasons ...

In my July 2005 column, a new ASTM standard shear test method was introduced 1. At that time, I raised the question, Why do we need another shear test method for composite materials?, with the promise ...
