## amplitude

(ˈæmplɪˌtjuːd)
n
1. greatness of extent; magnitude
2. abundance or copiousness
3. breadth or scope, as of the mind
4. (Astronomy) astronomy the angular distance along the horizon measured from true east or west to the point of intersection of the vertical circle passing through a celestial body
5. (Mathematics) maths Also called: argument (of a complex number) the angle that the vector representing the complex number makes with the positive real axis. If the point (x, y) has polar coordinates (r, θ), the amplitude of x + iy is θ, that is, arctan y/x. Compare modulus2 See also Argand diagram
6. (General Physics) physics the maximum variation from the zero or mean value of a periodically varying quantity
[C16: from Latin amplitūdō breadth, from amplus spacious]

4. the absolute value of the maximum displacement from a zero value during one period of an oscillation.
5. the maximum deviation of an alternating current from its average value.

## am·pli·tude

(ăm′plĭ-to͞od′)
One half the full extent of a vibration, oscillation, or wave. The amplitude of an ocean wave, for example, is the maximum height of the wave crest above the level of calm water, or the maximum depth of the wave trough below the level of calm water. The amplitude of a pendulum swinging through an angle of 90° is 45°. See more at wave.

Asymmetric stress-controlled ratcheting tests have been carried out at 300[degrees]C with various combination of mean stress and stress amplitude.
