Abstract:
Systems and methods for determining a damage value of one or more composite components and/or a vehicle using digital image correlation are disclosed. Digital image correlation is used to evaluate a displacement of one or more nanoparticles that are deposited on and/or embedded within the composite component. Digital image correlation is performed by identifying a first reference entry indicating a reference position of the one or more nanoparticles and correlating the first reference entry with sensor data of the composite component indicating a position of the one or more nanoparticles. The damage value of the composite component is determined based on the digital image correlation between the sensor data and the first reference entry.
