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:
“... the big courageous acts of life are those one never hears of and only suspects from having been through like experience. It takes real courage to do battle in the unspectacular task. We always listen for the applause of our co-workers. He is courageous who plods on, unlettered and unknown.... In the last analysis it is this courage, developing between man and his limitations, that brings success.”
—Alice Foote MacDougall (1867–1945)
“I conceive that the leading characteristic of the nineteenth century has been the rapid growth of the scientific spirit, the consequent application of scientific methods of investigation to all the problems with which the human mind is occupied, and the correlative rejection of traditional beliefs which have proved their incompetence to bear such investigation.”
—Thomas Henry Huxley (1825–95)
