Measuring of Vibration-Damping Properties of Cast Iron

Petra Kováčiková, Ján Vavro, Ján Vavro jr., Andrej Dubec
Nowadays, ever increasing demands are being made on equipment and machine structures. This fact negatively affects their lifespan, reliability and security. Internal damping is caused by material malfunctions in the microstructure, thermoelastic effects, movement of dislocations or the effects of swirling currents. This paper deals with microstructure, chemical composition and mechanical properties of ductile iron. These data are required as input parameters for computational modeling and
