Stress Functions - Airy Stress Function

The Airy stress function is a special case of the Maxwell stress functions, in which it is assumed that A=B=0 and C is a function of x and y only. This stress function can therefore be used only for two-dimensional problems. In the elasticity literature, the stress function is usually represented by and the stresses are expressed as

 \sigma_x = \frac{\partial^2\varphi}{\partial y^2} ~;~~ \sigma_y = \frac{\partial^2\varphi}{\partial x^2} ~;~~ \sigma_{xy} = -\frac{\partial^2\varphi}{\partial x \partial y}

Famous quotes containing the words airy, stress and/or function:

    Dull sublunary lovers’ love,
    Whose soul is sense, cannot admit
    Absence, because it doth remove
    Those things which elemented it.

    But we by a love so much refined
    That our selves know not what it is,
    Interassured of the mind,
    Careless eyes, lips, and hands to miss.

    Our two souls therefore, which are one,
    Though I must go, endure not yet
    A breach, but an expansion,
    Like gold to airy thinness beat.
    John Donne (1572–1631)

    A society which is clamoring for choice, which is filled with many articulate groups, each urging its own brand of salvation, its own variety of economic philosophy, will give each new generation no peace until all have chosen or gone under, unable to bear the conditions of choice. The stress is in our civilization.
    Margaret Mead (1901–1978)

    Philosophical questions are not by their nature insoluble. They are, indeed, radically different from scientific questions, because they concern the implications and other interrelations of ideas, not the order of physical events; their answers are interpretations instead of factual reports, and their function is to increase not our knowledge of nature, but our understanding of what we know.
    Susanne K. Langer (1895–1985)
