Recently, various types of high damping materials are widely used for suppressing vibrations in order to develop quit machines and create comfortable life spaces. However, those damping characteristics are generally evaluated experimentally. In this paper, the damping characteristics of a metal are investigated analytically. A dynamical analytical model of steel molecules is established and the molecule behaviors of a metal are investigated in order to study the viblation damping mechanism. Iron is treated here. As a first step, fundamental vibration characteristics and the energy dissipating characteristics are studied in an adiabatic condition for the initial offset condition.
