  • Compressive strength - Wikipedia

    OverviewIntroductionDeviation of engineering stress from true stressComparison of compressive and tensile strengthsCompressive strength of concreteSee also

    Compressive strength or compression strength is the capacity of a material or structure to withstand loads tending to reduce size, as opposed to which withstands loads tending to elongate. In other words, compressive strength resists being pushed together, whereas tensile strength resists tension (being pulled apart). In the study of strength of materials, tensile strength, compressive strength, and shear strength can be analyzed independently.
