Flight envelope protection using flap hinge moment measurement
… 106 and 1.0 × 106. The effects of six different simulated contamination configurations on the performance characteristics of both airfoils were tested. These configurations consisted of glaze ice, rime ice, two severities of distributed leading-edge roughness, three-dimensional leading-edge …

Structural Health Monitoring Using Smart Sensors
The damage detection capability and autonomous operation of the developed system are then experimentally verified. The SHM system consisting of ten Imote2s are installed on a scale-model truss. The SHM system monitors the truss in a distributed manner to localize simulated damage. Successful …

Damage detection in structures using frequency response function (FRF) data and finite element modelling
… thesis presents a method to detect structural damage using frequency response function (FRF) data obtained from non-destructive vibration tests. The method is used to study cases of early structural damage in which there is no appreciable change in mass and damping. The resulting change in …

Fe Modeling In Support Of Vibration Based Damage Detection In Bridges
Vibration based damage detection in bridges is examined with the objective of defining a relationship between substructure stiffness degradation and frequency and mode shape modulation induced by damage. The relationship is explored through finite element modeling of primarily an experimental …

The infuence of hail on wind turbine blade leading edge erosion and damage
Wind turbine blade damage, particularly leading edge erosion, is a signifcant problem faced by the renewable energy industry. Wind turbines are subject to a wide range of environmental factors during a 20+ year lifespan, with hailstones often touted as a key contributor to the deterioration of …

Benchmark Studies For Structural Health Monitoring Using Analytical And Experimental Models
… incidents, anomalies due to deterioration and damage during regular operation as well as after an extreme event. Dynamic testing and analysis are concepts widely used for health monitoring of existing structures. Successful health monitoring applications on real structures can be achieved by …
