Modeling Soil, Sand Or Snow Under Pressure (IMAGE)
Caption
Researchers have developed a new way to measure the forces inside materials such as sand, soil or snow under pressure. Using a solution of hundreds of translucent hydrogel beads in a Plexiglass box to simulate soil, sand or snow, the technique relies on lasers coupled with force sensors, cameras and advanced computer algorithms to measure the forces between neighboring particles in 3-D.
