Research output: Contribution to journalArticlepeer-review


A range of typical packing systems were examined and the unit cells were established for micromechanical analysis of particle-reinforced composites. The unit cells were capable of dealing with problems involving reinforcing particles of irregular geometries and local imperfections. The unit cells established could be subjected to arbitary combinations of macroscopic stresses or strains using a single set of boundary conditions. The effective properties of the composite represented by the unit cells were obtained through the analysis.
