Abstract

The objective of this paper is to develop appropriate algorithms to locate and size damage in plate structures. Two methods, one using the changes in the compliance distribution and the other using the changes in the modal strain energy, are presented in this paper. A damage index, used to identify possible locations and corresponding severities of local damage, is defined and expressed in terms of modal displacements that are obtained numerically from mode shapes of the undamaged and the damaged structures. The possible damage locations in the structure are determined by the application of damage indicators according to previously developed decision rules. Each of the two methods is demonstrated using a numerical example of a simply supported plate with simulated damage.
