A **force chain** is a concept primarily used in the fields of materials science, physics, and engineering to describe the way forces are transmitted through a granular material or a system of interconnected particles. In a force chain, the particles or grains that come into contact with each other transmit force from one to another, creating a network or "chain" of forces throughout the material. This concept is particularly relevant in the study of granular materials like sand, gravel, and other particulate substances.
