FBG_SiMul V1.0: Fibre Bragg grating signal simulation tool for finite element method models

Abstract

FBG_SiMul V1.0 is a tool to study and design the implementation of fibre Bragg grating (FBG) sensors solutions in any arbitrary loaded structure or application. The software removes the need for a fibre optic expert user and makes the sensor response of a structural health monitoring solution using FBG sensors more simple and fast. The software uses a modified T-Matrix method to simulate the FBG reflected spectrum based on the stress and strain from a finite element method model. The article describes the theory and algorithm implementation, followed by an empirical validation.
