  • CorrosionpediaWhat is a Compressive Strength

    Compressive strength is measured on materials, components and structures. By definition, the ultimate compressive strength of a material is that value of uniaxial compressive stress reached when the material fails completely. Measurements of compressive strength are affected by the specific test methods and conditions of measurement.
