Rapid prototyping algorithm for Customized Crack Propagation Sensors for SHM

In SHM systems, damage to supporting structure elements is detected using an integrated network of sensors operating in real-time or periodically in a frequent time stamps. Due to the need of placement such sensors in different parts of the component (e.g. airframe of the aircraft), it is necessary to develop a rapid prototyping algorithm that will enable the design of sensors of various shapes and configuration. The paper presents an algorithm based on an application created in LabVIEW software, which, based on data entered by the user, generates two spreadsheets formatted by the requirements of Autodesk Inventor and COMSOL Multiphysics software. As a result, a tailored in shape, the customized crack propagation sensor (CCPS) layout is prepared. A parametric model of the sensor was prepared in Autodesk Inventor software, which automatically changes its geometric dimensions after changing data in an MS Excel spreadsheet. Additionally, some results of simulation tests carried out in the COMSOL Multiphysics software using a parametric sensor model were also delivered.
