Compressive stress is the force applied perpendicular to a material's cross-section. It is the opposite of tensile stress which is applied in the opposite direction. Compressive stress is a type of stress that is used to reduce a material’s size, increase its density, and prevent it from breaking apart. Under compressive stress, materials respond by either compressing or shrinking depending on their elasticity. The amount of compressive stress required to cause a material to change shape is related to the material's Young's Modulus, which is the ratio of stress to strain. Compressive stress is used in many applications such as in the construction of buildings, bridges, foundations, and other structures. Compressive stress also plays an important role in the design of materials used in aircraft, automobiles, and other machines.
