The objective function F to be minimized utilizes the two modal correlation criteria (MACFLEX and MTMAC), while the design variable [d.sub.i] describes the extent of damage of the i-th element of the structure.
In this study, a combined objective function has been implemented, which takes into account the values of two different modal correlation criteria (MTMAC and MACFLEX) that express the relationship between the real (experimentally measured) damage and the damage which is numerically predicted by the finite element model.
In this numerical example, all individual criteria, [F.sub.1] (based on MTMAC), [F.sub.2] (based on MACFLEX), and F (combined), are examined and compared to each other.
