FBGs Real-Time Impact Damage Monitoring System of GFRP Beam Based on CC-LSL Algorithm

Glass-fiber reinforced polymer (GFRP) composite materials have an undisputed dominance over conventional metallic materials. However, susceptibility to barely visible or invisible internal damage due to impact has increased the demand for these composite materials in robust real-time structural he...

The CC-LSL algorithm also revealed that the highest percentage of error was only 4.21% away from the actual hit.
