Summary: Recent developments of material science are related to the modification of structure and properties of traditionally used alloys. Higher fatigue durability can be obtained by precision treatment of surface. High-temperature ceramic coating can improve the operating temperatures. Smart coatings can further sustain severe operating conditions. Life prediction methods are developed for fatigue and fracture of structural materials to enhance operation safety and more effective use of the structural health monitoring system.

Dimitris Saravanos
Dept. of Mechanical Engineering & Aeronautics, University of Patras, Greece
Summary: In this presentation we will first review research work on active SHM methods based on the linear wave propagation of Lamb waves. Numerical results from semi-analytical solutions and FEA models will illustrate the propagation of guided waves in laminated composite strips. Experimental results will further demonstrate the capability of ultrasonic Lamb waves to detect small delamination cracks, matrix cracks and impact damage in composite strips.
