To reduce the computational effort of this complex problem, a refined algorithm is implemented which identifies the parameters of a structure’s fini

To overcome this limit, the use of sensitivity enhancement techniques has recently proposed: the monitored structure is coupled to an auxiliary system, the constitutive parameters of which are then suitably tuned to enhance the sensitivities relevant to the identifi

A new approach is proposed which considers the peculiar aspects of the damage identification problem. Some applications of the technique proposed are outlined with reference to numerical and experimental cases.
