Beetles are creatures with built-in body armor. They are tiny tanks covered with hard shells, also known as exoskeletons, protecting their soft, skeleton-less bodies inside. In addition to providing ...

The properties of steel can be improved in terms of fatigue, weldability, hardness, wear and corrosion resistance, ductility, and tensile strength by either alloy addition or heat treatment processes.

In addition to providing coloration, the exoskeletal shell of beetles needs to be strong and damage tolerant, researchers explain. Beetles are creatures with built-in body armor. They are tiny tanks ...
