- W2186105021 abstract "In this paper, a damage detection technique based on force reconstruction is proposed to predict the position of the damage from the measured wave response of the structure. The technique is found to be efiective for cases where the additional waves resulting from the damage gets cluttered with the waves originating due to re∞ections from the boundaries and other discontinuities. In such cases, it is not possible to obtain their time of arrival directly from the response. When the force is reconstructed from these damaged response, one gets only the applied force and few uncluttered waves which originates due to the damage. As a result the time of arrival can be easily obtained from this reconstructed force and hence the position of the damage can be predicted. A wavelet based spectral flnite element model of undamaged structure is used for force reconstruction from the given wave response. The e‐ciency of the proposed method has been explained through numerical example of axial wave propagation in an isotropic rod with a degraded zone representing the damage. In the later part of the paper, the method is extended to detect de-lamination and other forms of damages in composite beams and laminated composite plates with symmetric and asymmetric ply-layup." @default.
