报告简介：
High performance at lower weight is the main challenge of recent structures in automotive and aerospace applications. A failure of these high performing parts will be catastrophic as no more structural reserves can be activated after exceeding limit load or service goal due to the optimization of the parts. Hence, the monitoring of the structural integrity of such high performing structures becomes vital. As scheduled inspections increase costs, to establish a Structural Health Monitoring (SHM) system which is running during service is the goal. This system has to be reliable, durable and efficient, as the structure’s integrity has to be assessed in runtime.
In this talk an SHM approach will be presented which is based on the intensive use of structural information of the sizing process. With this information specific Structural Damage Indicators (SDI) are derived which are monitored. As not the damage itself but the Structural Damage Indicator is the object of interest the design of the SHM system can be optimized in terms of accessibility, reliability and sensitivity. In addition to this the structural integration of the SDI monitoring sensors is possible which offers new opportunities in terms of robustness. At RWTH Aachen University a network of 15 institutes is following this approach. The collaboration results in a first composite part with an integrated SHM system which demonstrates the feasibility of the presented approach.

Prof. Dr.-Ing. Schröder graduated in civil engineering in 1999 at Leibniz University Hannover. In 2005 he completed his PhD thesis at the Institute of Structural Analysis of Leibniz University Hannover. Subsequently, he worked as a senior engineer and project manager at the ELAN GmbH Hamburg, now ELAN-AUSY, being in charge of the method and tools development for the Airbus research projects of the A380, A400M and A350 programs. In 2010, he became Assistant Professor at the Institute of Constructional Lightweight Design at the Johannes Kepler University of Linz, Austria. In 2013, he became a full Professor at RWTH Aachen University at the chair of engineering mechanics and since August 2014 he is Professor at the Institute of Structural Mechanics and Lightweight Design. He is a full member of LTH Structural Analysis (IASB) since 2006. His main field of interest comprises Methods & Optimization, Dynamics & Aeroelasticity, Structural Durability & Structural Health Monitoring as well as Space Structures.
