Description	This paper shows an efficient methodology based on micromechanical framework and grid nanoindentation for the assessment of effective elastic properties on several types of microscopically heterogeneous structural materials. The grid nanoindentation and statistical deconvolution methods previously described in the literature e.g. for cementitious materials, alkali activated materials or high-performance concretes [4] have been employed. In this paper we demonstrate their utilization also for other types of structural composites with crystalline nature and we validate the results by using enhanced numerical method based on fast Fourier transform (FFT). The direct procedure of using grid nanoindentation data in the FFT method simplifies the evaluation of effective composite properties and leads to the assemblage of the full stiffness matrix compared to simple analytical approaches.
