SIMPLE HARMONIC MOTION
... Motion that repeats itself over time is called periodic motion. The time to complete one cycle of the motion is called the period, T. The frequency f = 1/T, is the number of cycles of motion per second. Oscillatory motion is periodic motion where the displacement from equilibrium varies from a maxim ...

... Since the stress power is the double contraction of the Cauchy stress and rate-ofdeformation, one says that the Cauchy stress and rate of deformation are work conjugate (or power conjugate or energy conjugate). Similarly, from 3.8.26, the PK1 stress P is power conjugate to F& . It can also be shown ...
