what is 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. The compressive strength is usually obtained experimentally by means of a compressive test.y definition, the ultimate compressive strength of a material is that value of uniaxial compressive stress reached when the material fails completely.
