Sažetak
In this paper, the strain energy method using deflection influence surfaces of plate-like structures is used to detect and locate the damage. The use of numerical differentiation procedures is identified as the main cause for the poor performance of the strain energy method under sparse and noisy measurement. The bicubic interpolation is employed to interpolate measured values of the deflection influence surface. The strain energy damage detection method by using interpolated values has been compared by the same method which uses only the measured values of the deflection influence surface.
