Abstract: A multi-particle unit cell model of PMMA/ATH composite with different volume fractions was employed to study the influence of interphase properties and inter-particle distance on elastic modulus. The model constitutes amorphous polymer matrix, rigid fillers and interphase between filler and matrix. Polymer matrix was modelled using a thermodynamically consistent dual-mechanism viscoplastic model, whereas fillers were assumed as linear elastic. In numerical simulations, the interphase between filler and matrix was modelled through a user defined interphase model and matrix material was modelled through a user defined material model.
