Analysis Methods
The analysis of stress within a body implies the determination at each point of the body of the magnitudes of nine stress components. In other words, it is the determination of the internal distribution of stresses. An alternative method used in stress analysis is the determination of the internal distribution of strains.
A key part of analysis involves determining the type of loads acting on a structure, including tension, compression, shear, torsion, bending or a combination of some of these loads. When forces are applied repeatedly nearly all materials will rupture or fail at a lower stress than they would under a steady state load condition. The analysis to determine stresses under these cyclic loading conditions is termed fatigue analysis and is often applied to aerodynamic structural systems.

Famous quotes containing the words analysis and/or methods:
“Analysis as an instrument of enlightenment and civilization is good, in so far as it shatters absurd convictions, acts as a solvent upon natural prejudices, and undermines authority; good, in other words, in that it sets free, refines, humanizes, makes slaves ripe for freedom. But it is bad, very bad, in so far as it stands in the way of action, cannot shape the vital forces, maims life at its roots. Analysis can be a very unappetizing affair, as much so as death.”
—Thomas Mann (1875–1955)
“The philosopher is in advance of his age even in the outward form of his life. He is not fed, sheltered, clothed, warmed, like his contemporaries. How can a man be a philosopher and not maintain his vital heat by better methods than other men?”
—Henry David Thoreau (1817–1862)
