Granular materials are collections of discrete particles, such as sand, gravel, or rice. These materials can flow like liquids but also have the ability to support weight like solids. Their behavior depends on factors like particle size, shape, and moisture content, making them unique in various applications. Common examples of granular materials include soil, powdered sugar, and grains. They are essential in construction, agriculture, and many industrial processes. Understanding how these materials interact helps engineers and scientists design better structures and improve processes involving bulk materials.
