Finite element analysis of embedded optical fibre sensors

Abstract

Micromechanical Finite Element (FE) analysis was used to model stress and strain fields in and around embedded optical fibres EOF'S) in flexural test coupons of carbon fibre composite. The coupons were used in studies of EOF effects on macroscopic laminate properties. The FE method allows complex material inhomogeneities, laminate boundaries and load conditions to be modelled
