The damping properties of rubber decrease as strain amplitude increases due to the mechanical effects of wave propagation and internal friction. As rubber is stretched, the speed of wave propagation is influenced by the tension in the material, which alters interaction times for internal friction. Additionally, the chemical and physical interactions during compression and stretching affect molecular alignment and Van der Waals forces, leading to reduced damping. Understanding these factors is crucial for applications involving rubber materials.
