Recent investigations in granular media dynamics and impact mechanics have significantly advanced our understanding of how granular materials respond to intrusions, vibrations, and impacts across a ...

Tokyo, Japan - Researchers from Tokyo Metropolitan University have studied the properties of mixtures of silicone-coated "magic sand", a popular kid's toy, and normal sand. Silicone-coated sand ...

Johns Hopkins engineers have uncovered new details about how granular materials such as sand and rock behave under extreme impacts—findings that could someday help protect the Earth from dangerous ...

When we take a stroll on the beach, we walk on the sand without any trouble. The sand appears solid and is difficult to compress. When we put the same sand grains in an hourglass, they behave very ...
