We develop a real-coded constrained genetic algorithm (GA) and assess
its performance in selected classical optimisation problems. The proposed GA uses a roulette selection method, BLX-α crossover operation, non-uniform mutation along with single elitist selection
at every generation. The GA is then applied, in conjunction with the
finite element (FE) method, to optimise the damping response of a
laminate comprising unidirectional composite laminae and
viscoelastic damping layers. Modal loss factors are maximised
against the constraints of given structural stiffness and mass.
