Abstract
The present study aims to investigate the capability of new sensors to detect impact-induced damage in composite beams via VBM (Vibration-based Method). Laminated thermoplastic composite beams made of carbon fiber-reinforced polymer (CFRP) made of unidirectional layers are used as specimens in this investigation. Any deviation in vibrational parameters of beams such as mode shapes, natural frequencies, and more importantly frequency response functions (FRFs) by using damage metrics, before and after impact, will be considered as a criterion to identify damage and structural integrity degradation. Besides experimental procedure, numerical simulation of low-velocity impact and vibrational analyses of composite beams will be performed to evaluate the possible advantages/disadvantages of the computational procedure, as well as the potentialities and limitations of the new sensors to be used in SHM (Structural Health Monitoring) systems.
