The objective of this course is to prepare future experts to configure diagnosis systems for civil, offshore, aerospace and mechanical structures. To achieve this, so that the structures become lighter, damage is allowed to exist during operation as long as it is within safe, predetermined specifications. Course participants shall have the opportunity to learn about emerging technologies, dealing with the development and implementation of techniques and systems where automated monitoring, inspection and damage detection becomes an integral part of the structures. A major part of the lectures will be dedicated to composite materials increasingly used for ‘modern’ structures. Composite components are lightweight and have excellent fatigue and corrosion resistance. Failure of these structures is still less understood when compared to metals, and therefore it is still a matter of concern and specific attention. To cope with damage in those comparatively new materials, monitoring technologies and strategies are required in order to allow for the advantage of their light weight potential to be used on one hand, and not to compromise safety on the other. The aim of the course is therefore to describe and explain current research in areas of application and tendencies for the future of this technology including the various design issues. The theory and techniques that are important for understanding the topics covered will be addressed. Composite structures may be designed according to a damage tolerant philosophy, once the relevant technologies are available. Defects in those composite materials may arise during manufacture due to voids/ porosity, ply misalignment or inclusion of foreign microscopic particles that show no evidence to the naked eye. There is a list of examples of such defects: composite elements delaminated and/or contaminated by moisture (water, skydrol, etc.) or chemicals (silicon, etc.), thermal degradation and defects in composite bonds. Also surface contaminants of composite elements that appear during the manufacturing process are included in those examples. Damage mechanisms for such materials shall be thus covered, along with the latest developments in monitoring technologies. The objective of this lecture series is therefore also to get the basic knowledge from the field of smart structures that laterally encompasses disciplines such as structural dynamics, materials and structures, fatigue and fracture, non–destructive testing and evaluation, sensors and actuators, microelectronics, signal processing and many more. This also includes monitoring of external and internal loads with the goal of obtaining information about impacts or excessive fatigue loads in view of damage prognosis. A multidisciplinary approach among these disciplines is therefore required to holistically manage the operation of an engineering structure through its life cycle. The most commonly used methods are: active thermography, ultrasound including electro– mechanical impedance techniques, eddy current, terahertz technology (THz), and others including variations and combinations. The course is addressed to: students in post–graduate school (M.Sc. level); Ph.D. students; researchers interested in diagnosis of structural integrity and failures; practicing engineers interested in the field of health monitoring, maintenance, repair and overhaul.
