The volume 'Lamb-Wave Based Structural Health Monitoring in Polymer Composites' was published in September 2017. Over 480 pages, it presents the research results of eight years of research work supported by the German Research Foundation (Deutsche Forschungsgemeinschaft; DFG) on the subject of integrated component monitoring.

Integrated component monitoring (structural health monitoring, abbreviated to SHM), is an interdisciplinary technology field for monitoring damage in fibre-reinforced composite structures. Damage to the structure can be recorded and assessed using Lamb waves. Users and operators of the structure can thus continually monitor and assess its state and, if necessary, also schedule repair and maintenance work in good time.

This text book particularly focuses on the use of SHM technology on thin-walled components made from carbon-fibre-reinforced plastics. When special ultrasound waves, so-called Lamb waves, meet damage in the structure their signal changes, thus indicating the point in the component where a defect is present. The book is divided into four sections, the first three deal with analytical, numerical and experimental principles and the fourth section focuses on Lamb-wave propagation in fibre-reinforced composite materials, SHM systems and signal processing.

It is aimed not only at engineering students but also at researchers in the field of structural health monitoring and users of this technology.
