Abstract
This article offers a concise overview of cutting-edge techniques for monitoring bolt joint looseness and optimizing Macro Fiber Composite (MFC) based structure manufacturing for structural health monitoring emphasizing MFC-host structure attachment methods, optimal MFC placement, and the impact of adhesive layers between MFC and the host structure. The study also employs Ansys software to conduct Multiphysics modelling and characterization of bolt joint conditions using MFC piezoelectric transducers. Emphasizing joint looseness under varying pretension loads, the results demonstrate that increasing preload, up to the full tightening torque value (14.5 Nm), increases the natural frequency, indicating enhanced joint stiffness. Conversely, looser connections result in lower natural frequencies, signifying decreased joint stiffness. The article focuses on assessing the effectiveness of Macro-Fiber Composite (MFC) for monitoring the health of bolt joints, providing a simple and efficient method for modelling the structural response of MFC-integrated bolt joints, facilitating convenient and rapid engineering analysis and testing.
