A problem determining the shape and rigidity of inclusions embedded deformable materials is considered. This problem is a typical inverse problem to find the internal constitutive relations of materials from the boundary conditions on the external surfaces during deformation. Deformation is done by instrumented indentation, which measures the indentation load and the penetration depth dynamically. As the preliminarywork, we started with analyzing the data obtained by a sphere indentation testing simulated by finite element method. Particularly, the effect of sample size on the results of indentation testing was examined.
