Prediction and Measurement of Lamb Wave from Debondings at Structural Features in Composite Laminates Ching-Tai Ng1,a, Martin Veidt 2,b 1School of Civil, Environment & Mining Engineering, The University of Adelaide, Adelaide, South Australia, 5005, Australia 2School of Mechanical and Mining Engineering, The University of Queensland, Brisbane, Queensland, 4072, Australia aalex.ng@adelaide.edu.au (corresponding author), bm.veidt@uq.edu.au Keywords: Debonding, Lamb wave, scattering, finite element, composite laminates Abstract.
Introduction Cost effective and reliable safety diagnosis of engineering structures is a difficult task as the structures usually contains complex structural system.
In recent years composite materials (e.g. composite laminates) have been widely employed as primary structural components in different areas of engineering, such as civil and aerospace engineering, due to their high specific stiffness and light weight characteristics.
Composite laminates consist a number of fibrous composite material layers to provide required engineering properties.

Introduction Motivated by flying biosystems, flight engineering has been initiated since hundreds of years ago and has gradually grown from the time of Leonardo Da Vinci to Otto Lilienthal’s gliders to modern aircraft technologies and present flapping flight research.
While our understanding of fixed wing aerodynamics has been vastly advanced in the last one hundred years, leading to efficient and high performance aircraft of many kinds, despite substantial research effort, flapping wing aerodynamics remains a difficult and challenging subject [10].

Along with the continued search for advanced TE materials, the concept of FGM offers a strategy of gradual improvement of device performance.
The target of advanced techniques of materials preparation is to manufacture materials with controlled gradients in the TE properties which ensure optimum TE operation of a device.
One of the main points of this work consists in having shown that this comprehensive engineering information covers a case accurately describing a real system which is very close to the optimum of achievable performance.
