  2. Solid mechanics - Wikipedia

    en.wikipedia.org/wiki/Solid_mechanics

    A solid is a material that can support a substantial amount of shearing force over a given time scale during a natural or industrial process or action. This is what distinguishes solids from fluids, because fluids also support normal forces which are those forces that are directed perpendicular to the material plane across from which they act and normal stress is the normal force per unit area ...

  3. Theoretical strength of a solid - Wikipedia

    en.wikipedia.org/.../Theoretical_strength_of_a_solid

    When a solid is in tension, its atomic bonds stretch, elastically. Once a critical strain is reached, all the atomic bonds on the fracture plane rupture and the material fails mechanically. The stress at which the solid fractures is the theoretical strength, often denoted as . After fracture, the stretched atomic bonds return to their initial ...

  4. Strength of materials - Wikipedia

    en.wikipedia.org/wiki/Strength_of_materials

    Strengthening mechanisms that alter the strength of a material include work hardening, solid solution strengthening, precipitation hardening, and grain boundary strengthening. Strengthening mechanisms are accompanied by the caveat that some other mechanical properties of the material may degenerate in an attempt to make a material stronger.

  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.

  6. 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]

  7. Yield (engineering) - Wikipedia

    en.wikipedia.org/wiki/Yield_(engineering)

    This thus causes a higher yield stress in the material. While many material properties depend only on the composition of the bulk material, yield strength is extremely sensitive to the materials processing as well. These mechanisms for crystalline materials include Work hardening; Solid solution strengthening; Precipitation strengthening

  8. Elastic modulus - Wikipedia

    en.wikipedia.org/wiki/Elastic_modulus

    Homogeneous and isotropic (similar in all directions) materials (solids) have their (linear) elastic properties fully described by two elastic moduli, and one may choose any pair. Given a pair of elastic moduli, all other elastic moduli can be calculated according to formulas in the table below at the end of page.

  9. Solid-state physics - Wikipedia

    en.wikipedia.org/wiki/Solid-state_physics

    Solid-state physics is the study of rigid matter, or solids, through methods such as solid-state chemistry, quantum mechanics, crystallography, electromagnetism, and metallurgy. It is the largest branch of condensed matter physics. Solid-state physics studies how the large-scale properties of solid materials result from their atomic-scale ...
