High Damping Materials, Fundamental Aspects

Abstract

Any theoretical treatment of anharmonicity and 'soft modes' in real crystals is prodigious so it is useful to examine a very simple system just to see how anharmonicity couples normal modes together and affects certain physical properties. The system chosen is that of the one-dimensional coupled oscillators each of identical mass M coupled between two rigid (or non-rigid) walls by three identical springs. Mathematical expressions are provided and the thermodynamic relationships are expressed in this report. Steel and Nitinol are used for examples.
