Abstract

We present a method of damage identification of symmetrically laminated plates using bending deflection under static loading. The location of damage is first identified using an equation error approach based on residual forces. Then the magnitude of damage is evaluated using the nonlinear optimization technique. The effect of the number of measured deflection data on the identification results of the location and the magnitude of damage for symmetric laminates with one or two damage elements is examined.
