Abstract

Wave-based Structural Health Monitoring (SHM) to detect damages in civil and mechanical structures is a growing research field. In order to apply SHM to multi-wire cables, in this work, ultrasonic wave propagation in such coupled waveguides is studied theoretically, numerically and experimentally. In addition to transient finite element simulations, novel energy-based models are presented. With these models, efficient simulations of cables with many wires can be performed. Both finite element and energy-based models are verified with sophisticated experiments. [ABSTRACT FROM AUTHOR]
