structure

Unavoidable vibrations, such as those on airplanes, cause rigid structures to age and crack, but researchers have found that if you design them more like tooth enamel, it could lead to more resilient structures such as flight computers. Most materials that absorb vibration are soft and don’t make good structural components such as beams, chassis or motherboards. Artificial enamel is better than solid commercial and experimental materials that are aimed at the same vibration damping, as it’s lighter, more effective and less expensive. Researchers from the University of Michigan examined many structures in animals that had to withstand shocks and vibrations: bones, shells, carapaces and teeth. These living structures changed from species to species and over the eons. Tooth enamel told a different story. Under an electron microscope, it shared a similar structure whether it came from a Tyrannosaurus, a … Read more
