摘要：

In this paper, a computationally attractive damage index method is proposed for structural damage detection of cylindrical shell. It provides an insight to the extent of structural damage. Strain energy values computed for undamaged and damaged states are used in the corresponding damage index algorithms. It is derived from two parameters as moment response power spectral density and curvature response power spectral density. For all measured mode shapes, the damage index is defined by using the statistical parameter of relative root mean-square error of case before and after damage. The algorithm is applied to two numerical examples and its efficiency is demonstrated through damage simulations. (C) 2012 Elsevier Inc. All rights reserved.
