  2. Bulk modulus - Wikipedia

    en.wikipedia.org/wiki/Bulk_modulus

    The bulk modulus (or or ) of a substance is a measure of ... Solids can also sustain transverse waves: for these materials one additional elastic modulus, ...

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

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

    Elastic properties describe the reversible deformation (elastic response) of a material to an applied stress. They are a subset of the material properties that provide a quantitative description of the characteristics of a material, like its strength. Material properties are most often characterized by a set of numerical parameters called moduli.

  5. Elasticity (physics) - Wikipedia

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

    Young's modulus and shear modulus are only for solids, whereas the bulk modulus is for solids, liquids, and gases. The elasticity of materials is described by a stress–strain curve, which shows the relation between stress (the average restorative internal force per unit area) and strain (the relative deformation). [2]

  6. Elasticity tensor - Wikipedia

    en.wikipedia.org/wiki/Elasticity_tensor

    This fact follows from the symmetry of the stress and strain tensors, together with the requirement that the stress derives from an elastic energy potential. For isotropic materials, the elasticity tensor has just two independent components, which can be chosen to be the bulk modulus and shear modulus. [3]

  7. Lamé parameters - Wikipedia

    en.wikipedia.org/wiki/Lamé_parameters

    The two parameters together constitute a parameterization of the elastic moduli for homogeneous isotropic media, popular in mathematical literature, and are thus related to the other elastic moduli; for instance, the bulk modulus can be expressed as K = λ + ⁠ 2 / 3 ⁠ μ.

  8. Linear elasticity - Wikipedia

    en.wikipedia.org/wiki/Linear_elasticity

    In the isotropic case, the stiffness tensor may be written: [citation needed] = + (+) where is the Kronecker delta, K is the bulk modulus (or incompressibility), and is the shear modulus (or rigidity), two elastic moduli. If the medium is inhomogeneous, the isotropic model is sensible if either the medium is piecewise-constant or weakly ...

  9. List of materials properties - Wikipedia

    en.wikipedia.org/wiki/List_of_materials_properties

    Bulk modulus: Ratio of pressure to volumetric compression (GPa) or ratio of the infinitesimal pressure increase to the resulting relative decrease of the volume; Coefficient of restitution: The ratio of the final to initial relative velocity between two objects after they collide. Range: 0–1, 1 for perfectly elastic collision.
