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 ...

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 ...

Examples of granular matter: multicolored plastic balls in a playground, gravel, sesame seeds and lentils (clockwise from top left). Images by Julia Kertesz, Martin Olsson, Jitender Kumar and Zyance ...

The study of the rheology of suspensions and granular materials occupies a pivotal role at the crossroads of materials science, physics and engineering. This field examines how particulate systems ...

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 ...

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 ...
