Structural Health Monitoring of Wind Towers: Residual Life Estimation

Elastic-plastic fracture toughness and fatigue crack growth resistance of full penetration butt welds were experimentally investigated. The obtained results were used to predict the critical crack size and the time to structural collapse of weld joints typically adopted in tubular towers of windmills. For this purpose, heavy in-service loading conditions were considered. In this way, it was pos...

Investigation of waviness in wind turbine blades: Structural health monitoring

Waviness in composite wind turbine blades was detected and characterized with the help of air coupled ultrasonics. Based on the aspect ratio, the detected marcels are either accepted or rejected. A passive structural health monitoring approach has been presented here to monitor the accepted marcels above a threshold. The fatigue life of specimen is most affected in the presence of a marcel. Hen...

Implementing a Multiagent-Based Self-Managing Structural Health Monitoring System on a Wind Turbine

Deteriorations, increasing costs and burdens of maintenance work as well as recent collapses of civil engineering structures underscore the need for robust, cost-effective structural health monitoring (SHM) strategies. This paper describes the design and prototype implementation of a multi-agent software paradigm for a self-managing structural health monitoring system. As will be highlighted in...

A case study for application of fuzzy inference and data mining in structural health monitoring

In this study, a system for monitoring the structural health of bridge deck and predicting various possible damages to this section was designed based on measuring the temperature and humidity with the use of wireless sensor networks, and then it was implemented and investigated. A scaled model of a conventional medium sized bridge (length of 50 meters, height of 10 meters, and with 2 piers) wa...
