Study of Friction at the Mesoscale using Nitinol Shape Memory Alloy
Randall D. Peters
Elastic and dissipative properties of a NiTi shape memory alloy have been studied in both the martensite and austenite phases, using the free-decay of a vibrating Nitinol wire. The…
Friction as Basis for a Phonon Maser
Randall D. Peters
Evidence is provided from experiment, for the hypothesis that defect organization (internal friction) is a means for operation of a phonon maser.
Harmonic Oscillator Potential to describe Internal Dissipation
Randall D. Peters
Assuming that a constant potential energy function has meaning for a dissipated harmonic oscillator, then an important issue is the time dependence of the turning points. Turning p…
Intuitive Derivation of Reynolds Number
Randall D. Peters, Loren Sumner
It is evident from the literature that many engineers describe the Reynolds number qualitatively as ``the ratio of inertial forces to viscous forces''. Yet it is not immediately ob…
Ruchhardt Oscillator Decay- Thermodynamic basis for Hysteretic Damping
Randall D. Peters
Using thermodynamic arguments based on the ideal gas law, it is shown that hysteretic (also called structural) damping is the natural form of energy dissipation for this classic os…
The Flex-Pendulum -- Basis for an Improved Timepiece
Randall D. Peters
A compound pendulum of simple geometry was built from a lightweight rod to which a pair of masses are clamped, one above and the other below the axis of rotation. By making the pos…
