Improvement of the computational efficiency of metaheuristic algorithms for the crack detection of cantilever beams using hybrid methods

This study examines the capability of various optimization algorithms and proposes novel hybrid for more precise prediction open-edge cracks in cantilever beams. The natural frequencies beam with a crack are obtained by modal analysis experimentally validated impact testing. performance Harris hawk (HHO), electrostatic discharge algorithm (ESDA), pathfinder (PFA) Henry gas solubility (HGSO) from literature is evaluated to determine location depth an Euler–Bernoulli beam. Then, (HHO-NM, ESDA-NM PF-NM) proposed improve results aforementioned algorithms. Simulation show that yield much fewer function evaluations than previously introduced and, therefore, have superior detection capability. Statistical post hoc shows can be considered high-performance algorithm, which significantly efficiency applications.
