> Influences of strain amplitude on damping capacity of SiCp/Al composite Abstract: The dependence of the damping capacity of SiCp/Al composite at room temperature on strain amplitude has been simulated by employing cell method. The results show that the damping capacity of SiCp/Al composite is independent of the stain amplitude ε0 when ε0 is comparatively low. Meanwhile......
