This investigation examined the resonant vibration fracture behaviors of spheroidal graphite (SG) cast iron with various matrix structures. The results show that the vibration life is determined by a combined effect of the damping capacity and cracking resistance of the matrix. The structure surrounding graphite nodules also plays an important role since the stress concentrates in the vicinity of the nodules during vibration.
