= Critical state soil mechanics
{wiki=Critical_state_soil_mechanics}
Critical state soil mechanics is a theoretical framework used to describe the behavior of saturated granular soils (like sands and clays) under various stress conditions. Developed primarily by British engineer Alasdair Campbell, this approach provides a unified way to understand the relationships between stress, strain, and void ratio in soil, focusing specifically on the conditions under which soils reach a "critical state.
