<P>PROBLEM TO BE SOLVED: To provide a method for accurately defining a rubber material model for simulation from an actual rubber material. <P>SOLUTION: A method for simulating a rubber material including filler comprises: an imaging step S1 of acquiring an electron transmission image of a rubber material using a scanning transmission electron microscope; a step S2 of constructing a three-dimensional structure of the rubber material by a tomography method, from the image that has been acquired in the imaging step; and a model setting step of setting a rubber material model from the three-dimensional structure of the rubber material. The model setting step includes: a step S4 of dividing the rubber material into same-shaped basic elements partitioned by regular grids to set an initial rubber material model; a step S5 of setting segmented areas for further dividing the reference element, in a part of the initial rubber material model; and a step S6 of dividing only each element of the segmented area into two or more. <P>COPYRIGHT: (C)2013,JPO&INPIT |
