Damage detection is a research area that focuses on identifying and assessing damage in structures such as buildings, bridges, pipelines, and other infrastructure. This field involves using various sensors, monitoring techniques, and analysis methods to detect and locate damage, such as cracks, fractures, corrosion, or structural degradation. The goal of damage detection research is to develop reliable and accurate methods for assessing the condition of structures and detecting any potential issues early on, in order to prevent catastrophic failures and ensure the safety and integrity of the infrastructure.
