I'm trying to identify crack in cantilever beam using hybrid particle swarm and swallow swarm methods.I'm not clear about converting a crack into an objective function for an optimization problem.

Further, PSO codes in MATLAB can be downloaded from the following link;
What are different methods in PSO(Inertia, Cognitive coefficient C1 and C2, random value r) parameter tuning? - ResearchGate.

I hope it will be very helpful to you.
