Lamb Wave Propagation in Thermally Damaged Composites

The use of composites in primary and secondary structures of aerospace vehicles is important for increased performance with little weight penalty. Determining the response to thermal damage is necessary for a complete understanding of the total use environment of these materials. The objective of the research presented here is to provide a method of quantifying the amount of thermal damage in c...

Lamb Wave Propagation in Laminated Composite Structures

| Damage detection using guided Lamb waves is an important tool in Structural health Monitoring. In this paper, we outline a method of obtaining Lamb wave modes in composite structures using two dimensional Spectral Finite Elements. Using this approach, Lamb wave dispersion curves are obtained for laminated composite structures with different fibre orientation. These propagating Lamb wave modes...

Interactive Simulation and Visualization of Lamb Wave Propagation in Isotropic and Anisotropic Structures

Structural health monitoring systems allow a continuous surveillance of the structural integrity of operational systems. As a result, it is possible to reduce time and costs for maintenance without decreasing the level of safety. In this paper, an integrated simulation and visualization environment is presented that enables a detailed study of Lamb wave propagation in isotropic and anisotropic ...

Lamb Wave Propagation Modeling Using Cellular Automata

Theory of Lamb Wave propagation in plate-like structures have found many practical applications in Structural Health Monitoring. However for better understanding of complex physical phenomena associated with wave propagation and wave interaction with damage numerical simulations are as important as laboratory experiments. The paper shows the application of Cellular Automata technique for modeli...
