Assessment of cracks in beams using changes in the measured frequencies and Particle Swarm Optimization (2023)
Vibroengineering PROCEDIA Authors H. Greblă, Vasile Cătălin Rusu, Gilbert-Rainer Gillich, Thu Hang Bui Abstract This paper presents a method for detecting a crack in simply supported beams by identifying its location and severity (depth). The method is based on the measured natural frequencies for several bending vibration modes of an intact and cracked beam…
