Abstract

Identification of the delamination in fiber-reinforced composites, often used as aerospace and civil structures, is critical for structural health monitoring. It is well known that such a delamination affects the spectral characteristics (natural frequencies or mode shapes) of these structures. This study aims at developing numerical detection tools for identifying a single delamination in composite beam from its spectral data. The proposed mathematical models of delaminated composite beams will lead to the solutions of novel inverse transcendental eigenvalue problems (ITEP). Numerical techniques are developed here to solve such ITEP. It is demonstrated here that successful identification of damage parameters can be realized with finite number of spectral data set.
