Article Description

We employ chaotic interrogation of a circuit simulation of a structure in order to test for damage to the structure. The circuit simulation provides a realistic test of our attractor-based method and permits close control over parameters in the structure. In this circuit, simulating an eight-degree-of-freedom spring-mass system, we were able to detect changes of as little as 2% in the coupling between two oscillators in the circuit. This corresponded to detection of a 2% loss in stiffness to one spring in the modeled system. © 2003 The American Physical Society.
