This paper mmmarirrs the experimental program, rhe modal fesl results, the exrrocred modal shapes and an m&is implemented to localize the damage via modal strain energy distribution. The modal kw results consist of lhe vibrational signatures due m df&enr damages on rhe s,ruc,ure. The exrracted modal results are impiernenred in a global damqe detecrion/eualuation theory bared on modal swain ener...

The fuzzy logic concept provides a natural way of dealing with problems in which the source of imprecision is an absence of sharply defined criteria rather than the presence of random variables. The fuzzy approach considers cases where uncertainties play a role in the control mechanism of the concerned phenomena. Fuzzy modeling includes fuzzification, fuzzy analysis and defuzzification. In this...
