Vibration Analysis of Self-Healing Hybrid Composite Beam Under Moving Mass

In this study vibration analysis of hybrid epoxy composite beam under moving mass was investigated. Composite beam was reinforced unidirectional by carbon fibres and Shape Memory Alloy (SMA) wires. There is an open crack in the middle of the beam that is extended transversely in the beam structure...
