Non-linear internal friction and resonance in manganese-copper alloys

Internal friction and modulus at different amplitudes and frequencies were measured for as-cast Mn60Cu40 alloy. Strong non-linear internal friction and resonance were observed. It was proposed that the sources of these were derived from different factors. A parameter, P, which can be used to weigh up non-linear resonance of materials, is proposed. A high damping mechanism is discussed for manganese-copper alloy.
