Abstract
Advanced finite element techniques are used to analyse the mechanical stress and strain concentrations in and around an optical fibre embedded in a composite laminate. The models represent many features observed in real materials with embedded optical fibres. Three general laminate constructions were analysed with the optical fibre at the mid-plane and near the laminate surface. The models represent test coupons that are used to measure the effects of the embedded optical fibre on the laminate strength in tension and flexure; the applied loads and boundary conditions reflect these tests. Failure analysis is performed.Keywords
