Efficient temperature compensation strategies for guided wave structural health monitoring.
The application of temperature compensation strategies is important when using a guided wave structural health monitoring system. It has been shown by different authors that the influence of changing environmental and operational conditions, especially temperature, limits performance. This paper quantitatively describes two different methods to compensate for the temperature effect, namely opti...
متن کاملA Comparison of Temperature Compensation Methods for Guided Wave Structural Health Monitoring
The sensitivity to damage achievable by guided wave structural health monitoring systems is limited by the repeatability of recorded signals under normal operating conditions. Direct subtraction of reference signals leads to unacceptably high post-subtraction noise in the presence of modest temperature changes due to variations in reflections from benign structural features, hence temperature c...

متن کاملModeling guided wave propagation for structural health monitoring applications
In this paper a Semi-Analytical Finite Element (SAFE) method for modeling wave propagation in waveguides of arbitrary cross-section is discussed. The method requires the finite element discretization of the cross-section of the waveguide by assuming harmonic motion along the wave propagation direction. The general SAFE technique is extended to account for viscoelastic material damping by allowi...
متن کاملImpact of Applied Loads on Guided Wave Structural Health Monitoring
Guided wave structural health monitoring is a challenging problem, in part because of the complexity of signals received in a real structure containing geometrical features and boundaries. Signals scattered from damage can be one or two orders of magnitude smaller in amplitude than the direct arrival. Detection of these small, scattered signals is often accomplished by comparing signals of inte...
