Phase of vibration

any part of the path described by a particle or body in making a complete vibration, in distinction from other parts, as while moving from one extreme to the other, or on one side of the line of rest, in distinction from the opposite. Two particles are said to be in the same phase when they are moving in the same direction and with the same velocity, or in corresponding parts of their paths.

It is necessary to take into account, that statistically proved data on surface of contact differs within certain tolerance and phase of vibration from touching roughness profile is also unknown.
The impact of weld pressure and vibration amplitude and frequency on these variables, therefore, needs to be investigated using mathematical models for each phase of vibration welding.
The final phase of vibration welding, phase IV, in which the vibratory motion is stopped and the melt-film cools under pressure, is the most difficult to study experimentally because of its short and transient nature.
