  damage index
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.
      
Based on a small damage assumption, a damage index equation is revealedn the context of elasticity.
      
It turns out that the resulting damage index equation inherently suffers from singularities near inflection nodes.
      
With the aid of the singular value decomposition technique, the solution to the damage index equation is achieved in the Haar wavelet space.
      
Next, the physical desired solution to the damage index equation is reconstructed from the one in the wavelet space.
