  2. Plasticity (physics) - Wikipedia

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

    In physics and materials science, plasticity (also known as plastic deformation) is the ability of a solid material to undergo permanent deformation, ...

  3. Contact mechanics - Wikipedia

    en.wikipedia.org/wiki/Contact_mechanics

    An alternative definition of the plasticity index has been given by Mikic. [32] Yield occurs when the pressure is greater than the uniaxial yield stress. Since the yield stress is proportional to the indentation hardness σ 0 {\displaystyle \sigma _{0}} , Mikic defined the plasticity index for elastic-plastic contact to be

  4. Continuum mechanics - Wikipedia

    The study of the physics of continuous materials: Solid mechanics The study of the physics of continuous materials with a defined rest shape. Elasticity Describes materials that return to their rest shape after applied stresses are removed. Plasticity Describes materials that permanently deform after a sufficient applied stress. Rheology

  5. Plasticity - Wikipedia

    en.wikipedia.org/wiki/Plasticity

    Plasticity (physics), in engineering and physics, the propensity of a solid material to undergo permanent deformation under load; Behavioral plasticity, change in an organism's behavior in response to exposure to stimuli; Neuroplasticity, in neuroscience, how entire brain structures, and the brain itself, can change as a result of experience

  6. Flow plasticity theory - Wikipedia

    en.wikipedia.org/wiki/Flow_plasticity_theory

    Plastic deformation of a thin metal sheet. Flow plasticity is a solid mechanics theory that is used to describe the plastic behavior of materials. [1] Flow plasticity theories are characterized by the assumption that a flow rule exists that can be used to determine the amount of plastic deformation in the material.

  9. Hardness - Wikipedia

    en.wikipedia.org/wiki/Hardness

    Hardness is dependent on ductility, elastic stiffness, plasticity, strain, strength, toughness, viscoelasticity, and viscosity. Common examples of hard matter are ceramics, concrete, certain metals, and superhard materials, which can be contrasted with soft matter.
