Abstract:
Modern lightweight structures, particularly civil aircraft structures, are designed to tolerate certain levels of damage while maintaining structural health. It is considered and accepted that damages are present, as long as they are discovered early enough before reaching a critical size. Structural Health Monitoring (SHM), an emerging structure damage assessment methodology can support or even replace traditional elaborate inspection procedures by means of installed smart sensor networks. This talk investigates the structural health (i.e. strength) of damage tolerant lightweight structures during operation, on-line and over the entire lifetime of the structures. We’ll also examine new interdisciplinary research on structural analysis techniques, effects of damages in composite materials, implications of damages for lightweight constructions, and finally SHM methods and sensors placement to optimally identify critical damages.
Biographies:
Martin Schagerl received his PhD in mechanical engineering and a habilitation in mechanics from the Vienna University of Technology, Austria, where he also held the position of university assistant at the Institute of Mechanics from 1995 to 2002. Awarded a Max-Kade fellowship he visited the Mathematics Department of the University of Maryland in 2000/2001. In 2002 he started to work for the structure analysis department of Airbus in Hamburg, Germany. During this employment he contributed particularly to the aircraft programs A380, A400M, and A350. 2009 he moved to the Johannes Kepler University Linz, Austria, where he was appointed full professor and head of the Institute of Constructional Lightweight Design. Prof. Schagerl is member and since 2006 chair of the Industry Committee for Structural Analysis, the expert and editorial board of the Handbook Structure Analysis HSB.
Christoph Viechtbauer received his PhD in mechatronics from the Johannes Kepler University Linz, Austria. He joined the Institute of Constructional Lightweight Design as university assistant in 2010. Since 2014 he leads the research group of the Christian Doppler Laboratory for Structural Strength Control of Lightweight Construction which research focusses on static strength and fatigue life analysis of lightweight structures, effects of damages and manufacturing defects in composite materials, and mechatronic systems for Structural Health Monitoring. Dr. Viechtbauer is member and since 2014 business unit manager of the Association of German Engineers VDI in Austria.
