Abstract

A finite element micromodel has been developed based on real microstructures. The method of modelling is unique in that displacements calculated from large-specimen models are used as boundary conditions to model more accurately at the microstructural level. The development was centred around determining the response of the matrix, near a crack tip, to the constraint imposed by the particles. The process of developing the model is given and the final result is compared with experimentally measured values of constraint from the stereoimaging analysis of the photographs the model was based on. Good agreement was found and both techniques, stereoimaging and FEM, verified each other.
