Impact detection and localization remain very important aspects of the structural health monitoring system especially for composite structures. Composite structures typically have low damage tolerance and an impact may lead to barely visible or internal damage not visible in ordinary visual inspections. Hence a system that is able to detect and localize impact is invaluable for non-destructive testing inspectors. Such a system allows inspection of only the identified region which reduces downtime and inspection costs. Several techniques have been developed for impact detection. The problem with the localization is that most techniques depend on the time of arrival of the impact-induced waves and need information on the velocity of propagation of those waves for localization which is a challenge in an anisotropic composite. Furthermore, due to the structural complexity of the component, the velocity of propagation is not constant and it changes based on the ambient conditions. Hence, this work deploys a specially designed network which allows impact localization without knowing the velocity of propagation and in-turn without knowing the material properties. The work is carried out on carbon fiber-reinforced polymer composite subjected to hammer impacts.
