Molecular Simulation Analysis for the Influence of Hydrostatic Pressure on the Free Volume Fraction of Viscoelastic Damping Materials

The material studio molecular simulation analysis software was adopted to predict the free volume parameters of the two kinds of viscoelastic damping materials under static pressure. Prediction results showed that rising of the static pressure would lead to the decrease of the free volume parameters of the two materials,but the free volume parameters had decreases of various degree.
