Abstract: A component, a method of making a component and a method of monitoring strain. The component has an array of internal nodes with a radiopacity distinct from the predominant radiopacity of the component. Displacement of the nodes can be measured and used to calculate strain on the component.

Abstract: A monitoring system includes an acoustic emission monitoring system including acoustic emission sensors, a partial discharge monitoring system including partial discharge sensors and synchronized with the acoustic emission monitoring system, and a computer receiving acoustic emission data from the acoustic emission sensors and electrical data from the partial discharge sensors. The computer is configured to classify a first statistical event as a fatigue cracking event by pattern recognition of the acoustic emission data and determine a first location and a first damage condition resulting from the fatigue cracking event, classify a second statistical event as a partial discharge event by pattern recognition of the acoustic emission data or the electrical data, and fuse the acoustic emission data and the electrical data for the second statistical event and determine a second location and a second damage condition resulting from the partial discharge event. Methods of monitoring are also disclosed.

Abstract: A method of non-destructive testing includes locating an ultrasonic transducer with respect to a component having a visually-inaccessible structure to collect B-scan data from at least one B-scan of the component and to collect C-scan data from at least one C-scan of the component. The method also includes filtering the B-scan data and the C-scan data to remove random noise and coherent noise based on predetermined geometric information about the visually-inaccessible structure to obtain filtered data. The method further includes performing linear signal processing and nonlinear signal processing to determine a damage index for a plurality of voxels representing the visually-inaccessible structure from the filtered B-scan data and the filtered C-scan data to generate a V-scan image. A method of non-destructive testing of a wind turbine blade and an ultrasound system are also disclosed.

Abstract: A system and related methods for evaluating a component using a reference feature and a replicate of the reference feature. The component has an exterior surface with a reference feature thereon. The method includes determining an initial condition of the reference feature, subjecting the component to at least one duty cycle after determining the initial condition, determining a subsequent condition of the reference feature after the at least one duty cycle while the component is in a service position, and forming a replicate of the reference feature while the reference feature is in one of the initial condition or the subsequent condition. One of the initial condition or the subsequent condition may be determined based on the replicate of the reference feature.
