Evaluation of the appropriate size of the finite element representative volume for filled rubber composite analyses

The appropriate size of the representative volume element (RVE) for filled rubber composite is investigated where the volume fraction of the filler is about 20%. The micro structures of the composite are obtained by the measurement with 3-dimensional transmission electron microscope tomography (3D-T...
