Surface Energy - Calculating The Surface Energy of A Deformed Solid

Calculating The Surface Energy of A Deformed Solid

In the deformation of solids, surface energy can be treated as the "energy required to create one unit of surface area", and is a function of the difference between the total energies of the system before and after the deformation: .

Calculation of surface energy from first principles is an alternative approach to measurement. Surface energy is estimated from the following variables: width of the d-band, the number of valence d-electrons, and the coordination number of atoms at the surface and in the bulk of the solid.

Famous quotes containing the words calculating the, calculating, surface, energy, deformed and/or solid:

    What our children have to fear is not the cars on the highways of tomorrow but our own pleasure in calculating the most elegant parameters of their deaths.
    —J.G. (James Graham)

    [The] elderly and timid single gentleman in Paris ... never drove down the Champs Elysees without expecting an accident, and commonly witnessing one; or found himself in the neighborhood of an official without calculating the chances of a bomb. So long as the rates of progress held good, these bombs would double in force and number every ten years.
    Henry Brooks Adams (1838–1918)

    In Manhattan, every flat surface is a potential stage and every inattentive waiter an unemployed, possibly unemployable, actor.
    Quentin Crisp (b. 1908)

    I rather think the cinema will die. Look at the energy being exerted to revive it—yesterday it was color, today three dimensions. I don’t give it forty years more. Witness the decline of conversation. Only the Irish have remained incomparable conversationalists, maybe because technical progress has passed them by.
    Orson Welles (1915–1984)

    I should prefer a Woman that is agreeable in my own Eye, and not deformed in that of the World, to a celebrated Beauty. If you marry one remarkably beautiful, you must have a violent Passion for her, or you have not the proper Taste of her Charms; and if you have such a Passion for her, it is odds but it will be imbittered [sic] with Fears and Jealousies.
    Joseph Addison (1672–1719)

    Manuel showed her his open hand: “Look at this finger, how meager it seems, and this one even weaker, and this other one no stronger, and this one all by himself and on his own.”
    Then he made a fist: “But now, is it strong enough, big enough, solid enough? It seems so doesn’t it?”
    Jacques Roumain (1907–1945)
