Crack Detection In Cantilever Beams Using A New Hybrid Approach
Abstract— In the present work, a hybrid approach based on response surface methodology and genetic algorithm has been
developed to detect crack in cantilever beam type structures. In this paper, a numerical as well as an experimental study is
designed to predict a single open crack in cantilever beams. The crack is modeled using response surface methodology. The
weighted sum of the squared errors between the measured and computed natural frequencies is used as the objective function.
This objective function is minimized using genetic algorithm (GA) optimization technique. The results show that both the size
and location of the crack can be predicted well through this method.
