« Structural Health Monitoring (SHM) of structure and control systems »
Abstract:
The increasing demand for safety becomes nowadays a clearly visible trend in civil, structural and mechanical engineering. This is related to the fact that a large number of existing civil infrastructures reached their service life and a growing number of structures is equipped with Structural Health Monitoring (SHM) and control systems. The purpose of this seminar is to provide an overview of smart technologies for engineering applications. The seminar is dealing with both theoretical and computational aspects of engineering design related to structural topology optimization, semi-actively controlled structural connections and optimal layout of sensor network for large-scale structures. The seminar consists of three parts:
1) Structural topology optimization
Within this part a technology of 3D printed structures is introduced. Fully stress design approach is applied to find lightweight structure with minimal compliance.
2) Semi-actively controllable joints
This part of the seminar is devoted to development of control strategy allowing efficiently attenuate structural vibrations with minimal control effort.
3) Optimal sensor placement
Finally, basic concepts of optimal sensor placement methodology will be discussed. In particular, Fisher information matrix approach and convex relaxation is introduced to find optimal location of multi-type sensor network.
CV of the lecturer
Bartlomiej BLACHOWSKI is a member of the scientific staff of the Institute of Fundamental Tech- nological Research of the Polish Academy of Sciences (IPPT PAN). He received an MSc degree at the Silesian University of Technology in 2000, a PhD degree at IPPT PAN in 2005, and a habilitation degree at IPPT PAN in 2020. His research areas include wide-sense structural dynamics, in particular strategies of vibration control, algorithms for optimal structural design, and the use of sensor networks for structural health monitoring. He is equally interested in modern computational methods of struc- tural analysis, experimental techniques such as operational modal analysis, and hardware solutions for wireless acceleration measurements of engineering structures.
