    MODULUS OF ELASTICITY

    The ratio of stress


    applied to body or
    substance to the
    resulting strain
    within the elastic
    limit or elastic
    modulus.
    • Young's modulus, also known as the elastic
    b

    modulus , is a measure of the stiffness of a


    solid material
    • It defines the relationship between stress
    (force per unit area) and strain in a material.
    • Young's modulus is named after the 19th-
    century British scientist Thomas Young.
    • The term modulus is the root meaning of the
    Latin term modus which means measure.
    A solid material will deform when a load is
    applied to it. If it returns to its original shape
    after the load is removed, this is called Elastic
    Deformation. In the range where the ratio
    between load and deformation remains
    constant, the stress-strain curve is linear. Not
    many materials are linear and elastic beyond a
    small amount of deformation. A stiff material
    needs more force to deform compared to a soft
    material, and an infinite force would be needed
    to deform a perfectly rigid material, implying
    that it would have an infinite Young's modulus.
    Elastic modulus has the form.
    UNITS OF ELASTICITY
    Young's modulus is the ratio of stress (which has
    units of pressure) to strain (which is
    dimensionless), and so Young's modulus has
    units of pressure. Its SI unit is therefore the
    pascal (Pa or N/m2 or kg·m−1·s−2). The practical
    units used are megapascals (MPa or N/mm2) or
    gigapascals (GPa or kN/mm2).
    CALCULATION
    TENSILE ELASTICITY
    • Tensile elasticity is the tendency of
    an object to deform along an axis
    when opposing forces are applied
    along that axis; it is defined as the
    ratio of tensile stress to tensile strain.
    It is often referred to simply as the
    elastic modulus.
    TENSILE MODULUS
    SHEAR MODULUS

    The shear modulus or modulus of rigidity


    (G or μ) describes an object's tendency to
    shear (the deformation of shape at constant
    volume) when acted upon by opposing
    forces; it is defined as shear stress over
    shear strain. The shear modulus is part of
    the derivation of viscosity.
    SHEAR MODULUS
    BULK MODULUS
    • The bulk modulus (K) describes volumetric
    elasticity, or the tendency of an object to
    deform in all directions when uniformly
    loaded in all directions; it is defined as
    volumetric stress over volumetric strain,
    and is the inverse of compresibility. The
    bulk modulus is an extension of Young's
    modulus to three dimensions.
    BULK MODULUS
    SUMMARY
    Elastic Modulus is a measure of the
    stiffness of a solid material.
    Elastic modulus can be defined as:

    Unit of Modulus of Elasticity is Pascal.


    There are three types of modulus of
    Elasticity : Tensile Elasticity , Shear Modulus
    and Bulk Modulus
