  2. Contact mechanics - Wikipedia

    en.wikipedia.org/wiki/Contact_mechanics

    The following assumptions are made in determining the solutions of Hertzian contact problems: The strains are small and within the elastic limit. The surfaces are continuous and non-conforming (implying that the area of contact is much smaller than the characteristic dimensions of the contacting bodies).

  3. Specific heat capacity - Wikipedia

    en.wikipedia.org/wiki/Specific_heat_capacity

    In thermodynamics, the specific heat capacity (symbol c) of a substance is the amount of heat that must be added to one unit of mass of the substance in order to cause an increase of one unit in temperature. It is also referred to as massic heat capacity or as the specific heat. More formally it is the heat capacity of a sample of the substance ...

  4. Heat equation - Wikipedia

    en.wikipedia.org/wiki/Heat_equation

    A fundamental solution, also called a heat kernel, is a solution of the heat equation corresponding to the initial condition of an initial point source of heat at a known position. These can be used to find a general solution of the heat equation over certain domains; see, for instance, for an introductory treatment.

  5. Heat capacity - Wikipedia

    en.wikipedia.org/wiki/Heat_capacity

    Heat capacity or thermal capacity is a physical property of matter, defined as the amount of heat to be supplied to an object to produce a unit change in its temperature. [1] The SI unit of heat capacity is joule per kelvin (J/K). Heat capacity is an extensive property. The corresponding intensive property is the specific heat capacity, found ...

  6. Internal energy - Wikipedia

    en.wikipedia.org/wiki/Internal_energy

    The internal energy of a system depends on its entropy S, its volume V and its number of massive particles: U(S,V, {Nj}). It expresses the thermodynamics of a system in the energy representation. As a function of state, its arguments are exclusively extensive variables of state. Alongside the internal energy, the other cardinal function of ...

  7. Electrode - Wikipedia

    en.wikipedia.org/wiki/Electrode

    The physical properties of the electrodes play an important role in determining these quantities. Important properties of the electrodes are: the electrical resistivity, the specific heat capacity (c_p), the electrode potential and the hardness. Of course, for technological applications, the cost of the material is also an important factor. [12]

  8. Heat - Wikipedia

    en.wikipedia.org/wiki/Heat

    The molar heat capacity is the heat capacity per unit amount (SI unit: mole) of a pure substance, and the specific heat capacity, often called simply specific heat, is the heat capacity per unit mass of a material. Heat capacity is a physical property of a substance, which means that it depends on the state and properties of the substance under ...

  9. Self-similar solution - Wikipedia

    en.wikipedia.org/wiki/Self-similar_solution

    [11] [12] The governing equation when heat conduction is the primary heat transfer mechanism is the one-dimensional energy equation: = where is the material's density, is the material's specific heat capacity, is the material's thermal conductivity.
