Abstract: Dynamic loading tests were conducted on 1300φ lead rubber bearings using E-Isolation. FEM analysis calculated lead temperature changes using force and deformation data from these tests. We demonstrated that the relationship between yield stress and strain rate depends on temperature, and this follows the Arrhenius law. The activation energy of lead was determined, and yield force was formulated against lead temperature and strain rate. The derived equation matched well with existing experimental formulas and simulated well the experimental data.
