Abstract In this study we present an embedded element analysis methodology for predicting the onset of intra- and inter-laminar matrix failure. The embedded element methodology allows the two constituents, fibre and matrix, to be meshed independently, simplifying computational modelling of complex composite structures containing resin-rich regions, as a contiguous mesh is no longer needed. The work described herein focuses on the ability of the embedded element methodology to predict intralaminar failure in cross-ply laminates loaded in three-point bending. The results show that the embedded element methodology predicts the onset of matrix failure, which generally occurs below the ultimate structural fracture and is therefore conservative for design purposes. The location of failure onset is well predicted to coincide as experimental observations.
