Compressive Strength

A material′s ability to resist a force that tends to crush or buckle.

Compressive Strength is the maximum compressive load a specimen sustains divided by the specimen′s original cross-sectional area. Note: "Original" cross-sectional area.

The compressive strength of a material that fails by shattering fracture can be defined within fairly narrow limits as an independent property. However, the compressive strength of materials that do not shatter in compression must be defined as the amount of stress required to distort the material an arbitrary amount.
