| Abstract: | Internal friction at different amplitude and frequencies for as-cast Mn60Cu40 alloy was measured. Strong nonlinear internal friction and nonlinear resonance were observed. The results were analysed. A parameter (P) indicative to nonlinear resonance was introduced. The high damping mechanism in MnCu alloy was discussed. |
