The increasing application of laminated composite beams as structural load-bearing elements necessitates the understanding of the complex damage mechanisms of such materials and the development of reliable and easy-to-apply methods for timely damage detection. The use of damage detection methods based on vibration data together with robust computational algorithms in such materials appears to be a very good option due to its ease of application. Recent research in this field has accelerated and garnered significant industrial and scientific interest worldwide. However, the practical application of optimization methods in vibration-based damage detection for composites remains limited.In this study, the damage detection problem is solved by optimization based finite element model updating. A general anisotropic composite beam under various damage scenarios is considered. A new objective function based on vibration characteristics is used in the solution. The damage detection results using four different optimization algorithms (HSA, GA, TLBO, PSO) are presented comparatively.
