Finite Element Model of Structural Health Monitoring System Based on Ultrasonic Guided Waves on Remanufactured Components

Ultrasonic guided wave-based (UGW) structural health monitoring (SHM) is a sophisticated and invaluable process that employs an array of sensors and measurement devices to meticulously assess the ongoing performance and condition of various structures. Over time, accumulated data can facilitate the structural diagnosis, enabling informed maintenance decisions, and supporting remanufacturing efforts. SHM can play a key role in regeneration by providing valuable information on the condition of structures and components. This encompasses its capacity to ascertain the feasibility of remanufacturing, guiding determinations regarding the salvaging of reusable parts as opposed to the replacement of those that no longer meet operational standards. Moreover, SHM excels in its ability to pinpoint damage within structures and components, meticulously monitor the performance of remanufactured components, and ensure their alignment with predefined performance criteria. In this work, a finite element (FE) model of UGW-based SHM system on a aluminum plate, in pristine, damaged and remanufactured conditions, is presented. Notably, the wealth of SHM data gathered throughout the remanufacturing process can be strategically leveraged to refine the design of components and structures in subsequent iterations, thereby perpetually advancing the overall quality and efficiency of remanufactured products.
