Conference paperSalmanpour MS, Sharif Khodaei Z, Aliabadi MH, 2015,
A reference free method for damage detection and location based on geometric similarity
, Pages: 133-142This paper outlines a method exploiting geometrically similar areas as mutual baselines. The proposed method eliminates the need for previously recorded baseline sets and the pitfalls of changing environmental conditions between recording of signals. Through the use of instantaneously recorded baselines at the same time as the current interrogation signal and transducer calibration, it is possible to accurately predict the location of damage. The proposed transducer calibrated instantaneous baseline (TCIB) method was first applied to numerically simulated results. It was then validated experimentally for two different locations of artificial damage.

Assessment of delay-and-sum algorithms for damage detection in aluminium and composite plates
, Smart Materials and Structures, Vol: 23, Pages: 1-20, ISSN: 0964-1726Piezoelectric sensors are increasingly being used in active structural health monitoring, due to their durability, light weight and low power consumption. In the present work damage detection and characterization methodologies based on Lamb waves have been evaluated for aircraft panels. The applicability of various proposed delay-and-sum algorithms on isotropic and composite stiffened panels have been investigated, both numerically and experimentally. A numerical model for ultrasonic wave propagation in composite laminates is proposed and compared to signals recorded from experiments. A modified delay-and-sum algorithm is then proposed for detecting impact damage in composite plates with and without a stiffener which is shown to capture and localize damage with only four transducers.
