Fig. 8. ImageJ: Calculation of Crack length.

Fig.9 shows the propagation of the initial crack in different frames. At each moment in time, we measure the current length of the crack and the proportion of the frame's expected lifespan that has been exhausted. By analyzing the variation in the crack's length over time, we can gain insights into the structure's performance and identify potential areas for improvement. In this way, our methodology allows us to continually monitor the frame's health and make informed decisions about maintenance and repair.
