1. A method for predicting a deformation behavior of a rubber material, including: generating a three-dimensional model of the rubber material formed by adding a filler to a rubber; applying a configuration condition specifying a relationship between a stress and a strain on the basis of thickness information and temperature information obtained on the basis of a molecular dynamics approach to a rubber layer portion constituting the three-dimensional model; and, analyzing the deformation behavior of the rubber material, wherein the deformation behavior of the rubber material is analyzed by applying a finite element method to the three-dimensional model to which the configuration condition is applied, wherein the thickness information comprises information including a relationship between a distance from a filler surface and a diffusion coefficient of the rubber material, and wherein the temperature information comprises information including a relationship between a temperature and a diffusion coefficient of the rubber material.
