Plastic materials have been utilized in diverse products in a broad range of fields in recent years. Some of these include not only automotive parts such as bumpers, but also medical materials, daily ...

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 ...

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 ...

Measuring the “hardness” of soft, spongy elastomers—foams—is an inexact science. There is usually a surprisingly broad spread in the data normally provided by devices such as a durometer, a tool for ...

The use of instrumented indentation in materials testing includes its widespread application in measurements of Young’s modulus and hardness on limited volumes of test material. Such situations ...

Eddy current testing has been used for at least 50 years to inspect conductive parts for surface imperfections such as cracks or scratches. Fundamentally, the technique is comparative—it only ...

A simple, reliable way to predict new material properties is needed to facilitate modern technology development. Using a computational algorithm, Russian theorists have published a predictive tool in ...
