ABSTRACT:
A method of simulating deformation of a rubber material with a filler part made of one filler particle and a rubber part surrounding the filler pan, comprises the steps of: dividing the rubber material into a finite number of elements to form a rubber material model; performing deformation calculation of the rubber material model based on a predetermined condition; and acquiring necessary data from the deformation calculation; wherein the step of dividing includes the steps of: dividing the filler part into a finite number of elements to form a filler model; and dividing the rubber part into a finite number of elements to form a rubber model disposed around the filler model, the rubber model having strain-rate dependence such that the viscoelastic property varies with strain rate thereof.
