  2. Section modulus - Wikipedia

    en.wikipedia.org/wiki/Section_modulus

    The plastic section modulus is calculated as the sum of the areas of the cross section on either side of the PNA, each multiplied by the distance from their respective local centroids to the PNA. [16] = + where: A C is the area in compression A T is the area in tension y C, y T are the distances from the PNA to their centroids. Plastic section ...

    is the elastic modulus and is the second moment of area of the beam's cross section. I {\\displaystyle I} must be calculated with respect to the axis which is perpendicular to the applied loading. [ N 1 ] Explicitly, for a beam whose axis is oriented along x {\\displaystyle x} with a loading along z {\\displaystyle z} , the beam's cross section ...

  5. Flexural strength - Wikipedia

    en.wikipedia.org/wiki/Flexural_strength

    The flexural strength is stress at failure in bending. It is equal to or slightly larger than the failure stress in tension. Flexural strength, also known as modulus of rupture, or bend strength, or transverse rupture strength is a material property, defined as the stress in a material just before it yields in a flexure test. [1]

    In this case, the equation governing the beam's deflection can be approximated as: = () where the second derivative of its deflected shape with respect to (being the horizontal position along the length of the beam) is interpreted as its curvature, is the Young's modulus, is the area moment of inertia of the cross-section, and is the internal ...

  8. Properties of concrete - Wikipedia

    en.wikipedia.org/wiki/Properties_of_concrete

    The modulus of elasticity of concrete is relatively constant at low stress levels but starts decreasing at higher stress levels as matrix cracking develops. The elastic modulus of the hardened paste may be in the order of 10-30 GPa and aggregates about 45 to 85 GPa. The concrete composite is then in the range of 30 to 50 GPa.
