  2. Young's modulus - Wikipedia

    en.wikipedia.org/wiki/Young's_modulus

    Young's modulus is defined as the ratio of the stress (force per unit area) applied to the object and the resulting axial strain (displacement or deformation) in the linear elastic region of the material. Although Young's modulus is named after the 19th-century British scientist Thomas Young, the concept was developed in 1727 by Leonhard Euler.

  3. Elastic modulus - Wikipedia

    en.wikipedia.org/wiki/Elastic_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 compressibility. The bulk modulus is an extension of Young's modulus to three dimensions.

  4. Impulse excitation technique - Wikipedia

    en.wikipedia.org/wiki/Impulse_excitation_technique

    Different resonant frequencies can be excited dependent on the position of the support wires, the mechanical impulse and the microphone. The two most important resonant frequencies are the flexural which is controlled by the Young's modulus of the sample and the torsional which is controlled by the shear modulus for isotropic materials.

  5. Elastic properties of the elements (data page) - Wikipedia

    en.wikipedia.org/wiki/Elastic_properties_of_the...

    The elastic properties can be well-characterized by the Young's modulus, Poisson's ratio, Bulk modulus, and Shear modulus or they may be described by the Lamé parameters. Young's modulus [ edit ]

  6. Specific modulus - Wikipedia

    en.wikipedia.org/wiki/Specific_modulus

    Specific modulus is a materials property consisting of the elastic modulus per mass density of a material. It is also known as the stiffness to weight ratio or specific stiffness. High specific modulus materials find wide application in aerospace applications where minimum structural weight is required.

  7. Shear modulus - Wikipedia

    en.wikipedia.org/wiki/Shear_modulus

    The shear modulus is one of several quantities for measuring the stiffness of materials. All of them arise in the generalized Hooke's law: . Young's modulus E describes the material's strain response to uniaxial stress in the direction of this stress (like pulling on the ends of a wire or putting a weight on top of a column, with the wire getting longer and the column losing height),

  8. Bulk modulus - Wikipedia

    en.wikipedia.org/wiki/Bulk_modulus

    The bulk modulus (or or ) of a substance is a measure of ... and Young's modulus describes the response to normal (lengthwise stretching) stress. For a ...

  9. Stress–strain curve - Wikipedia

    en.wikipedia.org/wiki/Stress–strain_curve

    The stress is proportional to the strain, that is, obeys the general Hooke's law, and the slope is Young's modulus. In this region, the material undergoes only elastic deformation. The end of the stage is the initiation point of plastic deformation. The stress component of this point is defined as yield strength (or upper yield point, UYP for short
