(a) Young’s modulus map consisting of 64 measurements over a region . (b) The distribution of Young’s modulus values. The resulted in . (c) The data was accurately fitted to equation (12) since for each individual fit was close to 1. (d) Young’s modulus map over the same region using the proposed by this paper approach. (e) Young’s modulus distribution reveals that the new approach can be accurately used for Young’s modulus calculation under the condition that the sample presents a linear elastic behavior. (f) A mechanical property map in terms of . (g) The distribution of the values. The resulted in .
