Researchers have measured and identified for the first time the stress and strain shear modulus and internal friction of graphene sheets. Graphene is a material that has many potential groundbreaking ...

Many test methods are available for measuring the shear properties of composite materials. The V-notched methods are currently among the most popular, in part because they can produce a relatively ...

The offset shear strength is the shear stress endured by a material at the intersection of the shear stress versus the engineering shear strain curve, with a line parallel to a defined modulus and ...

Chemists and engineers have discovered a fundamental friction law that is leading to a deeper understanding of energy dissipation in friction and the design of two-dimensional materials capable of ...

Highly developed universal testing machines and custom testing systems are of use in running tests and the determination of properties, for example breaking strength, ductility, elongation, fracture ...

In digital circuits, insulating dielectrics separate the conducting parts (wire interconnects and transistors) from one another. As components have scaled down and transistors have gotten closer and ...

This file type includes high resolution graphics and schematics when applicable. However, this relationship between stress and strain in a material is linear only when the force applied is within ...
