The design process starts with determining the functional requirements of the component part. These requirements include: • Mechanical properties — tensile, compressive and flexural strength; ...

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 ...

In materials science, the hardness of a material measures its resistance to deformation by indentation, scratching or other physical actions. By this metric, plastics and soft tissues are said to be ...

BIRMINGHAM, Ala. - Yogesh Vohra, Ph.D., uses microwave-plasma chemical vapor deposition to create thin crystal films of never-before-seen materials. This effort seeks materials that approach a diamond ...

Knowing which material to use when designing or manufacturing a product is a very important skill to have. Different materials have a wide range of different properties. This means that choosing the ...

A new material is set to provide us with faster and higher resolution displays. Researchers explain what makes this material so special, opening the door to its application and further development. A ...

Each material has properties that make them good for specific tasks, eg cotton is lightweight and absorbent. The properties of materials must be considered when designing a product, eg a steel pan ...

Is it wizardry? Physicists at the University of Konstanz have succeeded in changing the properties of a material in a non-thermal way with the help of light and magnons. The new process is not only ...
