Nanoscopic Mechanical Simulation of Elastomers with Finite Element Analysis Keizo AKUTAGAWA Bridgestone Corporation, Kodaira, Tokyo, Japan Nippon Gomu Kyokaishi,(2009),82(5),227-232 General Review in Japanese Abstract Mechanical simulation technique for elastomers in nano-scopic scale range was reviewed. Combination of 3 dimensional transmission electron micro tomography (3D-TEMT) and 3 dimensional finite element analysis enables to investigate the deformation of elastomers in nano-scopic scale. The strain concentration over 200% can be seen between carbon black aggregates, even if the overall strain was only 15%. This is due to the fact that the occluded rubber can behave as a hard domain as if the volume fraction of filler is increased. It was found that the strain concentration between carbon black aggregates behaved as an important part of the reinforcement. Keywords: TEMT, Voxel, Computer Tomography, Occluded Rubber
