Damage localization and monitoring of load changes in truss structures
(2014) Mendrok, Krzysztof
In recent years one can observe an increasing interest of the researchers, both from academia and industry, in the development of systems for the monitoring of health structures. The main fields of application for these systems are rotating machinery, aircrafts and other means of group transport and civil engineering structures. Many of the latter, contain truss elements in its structure. That is why detection and possible localization of the fault in such a structures is crucial for the safety of its operation. In this paper the application of modal filtration to damage detection and localization in the truss structures is presented. The results of numerical simulation an laboratory experiment are shown.

Programmable logic devices as a tool in structure’s damage detection applications
(2013) Maj, Wojciech; Mendrok, Krzysztof; Barszcz, Tomasz
Programmable logic devices is one of the most dynamically developing fields of technology today. It is widely used in many kinds of signal acquisition as well as data processing systems mainly because of it’s large flexibility and continuously growing abilities. It gives a designer a powerful tool, which allows for the creation of almost any kind of logic topology and any kind of data processing system, which additionally may be freely reprogrammable without any physical changes in the platform device. This paper briefly describes programmable devices technology contribution in the development of various SHM (System Health Monitoring) systems. The SHM systems mentioned in this paper have already been designed, built and successfully tested on real structures.
