Health Monitoring for Composite under Low-Cycle Cyclic Loading, Considering Effects of Acoustic Emission Sensor Type
Composites have been widely used in the aerospace industry. Due to the requirement of a high safety for such structures, they could be considered for health monitoring. The acoustic emission approach is one of most effective methods for identifying damages in composites. In this article, standard specimens were made from carbon fibers and the epoxy resin, with the [03/902/...
متن کاملFlexural monitoring of carbon fiber/epoxy composite by acoustic emission
Carbon / epoxy composite is one of the most useful polymer matrix composites that has special properties such as high strength-to-weight ratio, high hardness, high corrosion resistance, Resistance to nuclear radiation has high consumption in different industries such as aerospace industry. Therefor monitoring of loading of this type of composite is important. In order to determine failure mecha...
متن کاملSmart Sensing Technology for Structural Health Monitoring
“Smart” sensors with embedded microprocessors and wireless communication links have the potential to fundamentally change the way civil infrastructure systems are monitored, controlled, and maintained. Indeed, a 2002 National Research Council Report [1] noted that the use of networked systems of embedded computers and sensors throughout society could well dwarf all previous milestones in the in...
متن کاملMonitoring of Metal Fatigue Damage Using Acoustic Emission and Thermography
Acoustic emission (AE) supplies information on the fracture behavior of different materials. In this study, AE activity was recorded in metal coupons with a V-shape notch, which were loaded in fatigue until final failure. AE parameters exhibit a sharp increase approximately 1000 cycles before final failure. The use of AE parameters is discussed both in terms of characterization of the damage me...
متن کاملExploitation of Acoustic Noise Correlation for Structural Health Monitoring Applications
Many recent studies in different domains exploited the ambient noise correlation to retrieve the Green’s function between two points. This technique allows a passive characterization of a given medium in the presence of a perfect diffuse field. The aim of this paper is to apply this principle in an aeronautic context. Thus we are looking to exploit the mechanical vibrations in a plane during th...
