In this video excerpt from NOVA's "Making Stuff: Stronger" , host and New York Times technology columnist David Pogue visits DuPont™, where Kevlar® was invented. After learning how this bulletproof ...

One material property that is widely used and recognized is the strength of a material. But what does the word "strength" mean? "Strength" can have many meanings, so let us take a closer look at what ...

The in-plane strength properties of a composite material, axial and transverse tension and compression and in-plane shear, are usually the first to be considered in design. However, ...

This video illustrates the tensile strength testing of a consumer-grade rope carried out using the Admet's eXpert 7603 universal testing machine. The tensile rope grips are modeled in such a way that ...

Back in April 2015, my CW column focused on the two ASTM standardized test methods used for measuring the through-the-thickness, or interlaminar, tensile strength of composite laminates. Despite their ...

If you’re serious about engineering the things you build, you need to know the limits of the materials you’re working with. One important way to characterize materials is to test the tensile strength ...

With industrialization gaining momentum in the United States and new construction sprouting up everywhere shortly after the end of the Civil War, there was a growing need for better ways to test the ...

Using Nanovea’s Mechanical Tester in indentation mode, with a cylindrical flat tip, it’s possible to obtain tensile-yield strength data that correspond directly to macro tensile data. Nanovea, a ...
