Fluid Mechanics - Relationship To Continuum Mechanics

Relationship To Continuum Mechanics

Fluid mechanics is a subdiscipline of continuum mechanics, as illustrated in the following table.

Rheology
Fluid mechanics
Non-Newtonian fluids do not undergo strain rates proportional to the applied shear stress.
Newtonian fluids undergo strain rates proportional to the applied shear stress.

In a mechanical view, a fluid is a substance that does not support shear stress; that is why a fluid at rest has the shape of its containing vessel. A fluid at rest has no shear stress.

Famous quotes containing the words relationship to, relationship, continuum and/or mechanics:

    Whatever may be our just grievances in the southern states, it is fitting that we acknowledge that, considering their poverty and past relationship to the Negro race, they have done remarkably well for the cause of education among us. That the whole South should commit itself to the principle that the colored people have a right to be educated is an immense acquisition to the cause of popular education.
    Fannie Barrier Williams (1855–1944)

    The proper aim of education is to promote significant learning. Significant learning entails development. Development means successively asking broader and deeper questions of the relationship between oneself and the world. This is as true for first graders as graduate students, for fledging artists as graying accountants.
    Laurent A. Daloz (20th century)

    The further jazz moves away from the stark blue continuum and the collective realities of Afro-American and American life, the more it moves into academic concert-hall lifelessness, which can be replicated by any middle class showing off its music lessons.
    Imamu Amiri Baraka (b. 1934)

    It is only the impossible that is possible for God. He has given over the possible to the mechanics of matter and the autonomy of his creatures.
    Simone Weil (1909–1943)
