Influence of Excitation Signal on Impedance-based Structural Health Monitoring
(Sage Publications Ltd, 2010-09-01)
The electromechanical impedance (EMI) technique has been successfully used in structural health monitoring (SHM) systems on a wide variety of structures. The basic concept of this technique is to monitor the structural ...
Artificial Immune Systems with Negative Selection Applied to Health Monitoring of Aeronautical Structures
(Trans Tech Publications Ltd, 2014-01-01)
In this paper we present a system for aircraft structural health monitoring based on artificial immune systems with negative selection. Inspired by a biological process, the principle of discrimination proper/non-proper, ...
A New Impedance Measurement System for PZT-Based Structural Health Monitoring
(Institute of Electrical and Electronics Engineers (IEEE), 2009-10-01)
Recent research has shown that electromechanical (E/M) impedance-based techniques are an efficient strategy for damage sensing in the context of structural health monitoring (SHM). The basic principle is to excite the lead ...
Time-Domain Electromechanical Impedance for Structural Health Monitoring
(European Assoc Structural Dynamics, 2011-01-01)
