  2. Compressive strength - Wikipedia

    en.wikipedia.org/wiki/Compressive_strength

    In mechanics, compressive strength (or compression strength) is the capacity of a material or structure to withstand loads tending to reduce size (compression). It is opposed to tensile strength which withstands loads tending to elongate, resisting tension (being pulled apart).

  3. Strength of materials - Wikipedia

    en.wikipedia.org/wiki/Strength_of_materials

    Compressive strength is a limit state of compressive stress that leads to failure in a material in the manner of ductile failure (infinite theoretical yield) or brittle failure (rupture as the result of crack propagation, or sliding along a weak plane – see shear strength). Tensile strength or ultimate tensile strength is a limit state of ...

  4. Compression (physics) - Wikipedia

    en.wikipedia.org/wiki/Compression_(physics)

    Compression of solids has many implications in materials science, physics and structural engineering, for compression yields noticeable amounts of stress and tension. By inducing compression, mechanical properties such as compressive strength or modulus of elasticity, can be measured. [5]

  5. Young's modulus - Wikipedia

    en.wikipedia.org/wiki/Young's_modulus

    Young's modulus is the slope of the linear part of the stress–strain curve for a material under tension or compression. Young's modulus (or Young modulus) is a mechanical property of solid materials that measures the tensile or compressive stiffness when the force is applied lengthwise. It is the modulus of elasticity for tension or axial ...

  6. Stress (mechanics) - Wikipedia

    en.wikipedia.org/wiki/Stress_(mechanics)

    This type of stress may be called (simple) normal stress or uniaxial stress; specifically, (uniaxial, simple, etc.) tensile stress. [13] If the load is compression on the bar, rather than stretching it, the analysis is the same except that the force F and the stress change sign, and the stress is called compressive stress.

  7. Compressive stress - Wikipedia

    en.wikipedia.org/wiki/Compressive_stress

    The ability of a material to withstand compressive stresses without failing is known as its compressive strength. When an object is subjected to a force in a single direction (referred to as a uniaxial compression), the compressive stress is determined by dividing the applied force by the cross-sectional area of the object. [1]

  8. Properties of concrete - Wikipedia

    en.wikipedia.org/wiki/Properties_of_concrete

    Engineers usually specify the required compressive strength of concrete, which is normally given as the 28-day compressive strength in megapascals (MPa) or pounds per square inch (psi). Twenty eight days is a long wait to determine if desired strengths are going to be obtained, so three-day and seven-day strengths can be useful to predict the ...

  9. Tensile structure - Wikipedia

    en.wikipedia.org/wiki/Tensile_structure

    The term tensile should not be confused with tensegrity, which is a structural form with both tension and compression elements. Tensile structures are the most common type of thin-shell structures . Most tensile structures are supported by some form of compression or bending elements, such as masts (as in The O 2 , formerly the Millennium Dome ...
