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 ...
Granular materials, from sands to engineered powders, exhibit complex mechanical behaviour that challenges traditional concepts of solid and fluid mechanics alike. Researchers have increasingly ...
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 ...
Jacqueline Reber receives funding from the Iowa State University College of Liberal Arts and Sciences Frontier Science Fund. Did you eat cereal this morning? Or have you walked on a gravel path? Maybe ...
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 ...
Researchers developed a method for 3D experiments that can reveal how forces are transmitted through granular materials, and how the shapes of the grains can dramatically change the outcomes. This ...
Itai Einav receives funding from Australian Research Council. What looks like ordinary sand, rocks or snow flowing in one direction can actually hide swirling currents that move in multiple directions ...
