Multiple Crack Detection in Beam-Like Structures Using a Novel Particle Swarm Optimization Approach (2025)
This paper presents a method for assessing two cracks in simply supported beams by identifying their locations and severities (depths). Our method is based on applying the Particle Swarm Optimization (PSO) algorithm with the measured natural frequencies for several bending vibration modes of an intact and cracked beam. We are using calculated relative frequency…
