This study examines the method of estimating the inner structure of soft materials with inclusions by means of hard sphere indentation. In experiments, indentation test with a ball indenter was performed using an elastic sample made of silicon rubber. We prepared 36 types of samples with inclusions with different diameters and positions. The reaction force was measured with load cell as a function of indentation points to obtain reaction profiles. As a result, it is shown that we can establish the method of estimating the shape and depth of inclusions inside the elastic body by performing the Gaussian fitting to the reaction force profiles.
