Abstract: Fibre Bragg Gratings (FBG) is an important class of optical fibre sensing devices that have been widely studied and applied in the field of Structural Health Monitoring (SHM), both in R&D settings and field applications. This project aims to build the virtual prototypes of a FBG-based pressure and a temperature-compensated strain sensor, as well as to predict their performance when being used for SHM (leak detection) of gas pipelines. Using Finite Element Analysis (FEA) in ANSYS®, the two prototypes were constructed and their responses to varying environmental conditions such as temperature and strain were simulated. The simulation results were further compared with physical experimental data for verification. Lastly, two methods of temperature compensation for the strain sensor were explored to demonstrate the usefulness of this simulation technique for improving performance of the sensors.
