“…This method has proven to be very accurate in calculating the orthotropic elastic moduli of materials from monotonic instrumented nanoindentation techniques and for nanomechanical characterization of thin film coatings. [ 46,63 ] In this work, an algorithm initially proposed in the study by Lamuta [ 74 ] is applied to find the orthotropic elastic constants of the material. It consists of finding the three main independent elastic moduli of the material ( E 11 , E 22 , and E 33 ) and the Poisson's ratios, assuming that the corresponding shear moduli ( G 44 , G 55 , and G 66 ) can be written as functions of the elastic coefficients mentioned earlier, i.e.

{\begin{matrix} G_{12} = \frac{E_{11}}{2 false(1 + ν_{12} false)} \\ G_{13} = \frac{E_{33}}{2 false(1 + ν_{13} false)} \\ G_{23} = \frac{E_{22}}{2 false(1 + ν_{23} false)} \end{matrix}

“…[40,41] This method requires relatively small samples in comparison with other methods, and allows the mechanical properties of a wide range of materials to be obtained, from thick solid specimens to thin film coatings of metallic or polymer sheets. [35,40,[42][43][44][45][46][47][48] Indentation procedures have for long been used for determining the surface hardness of metallic materials. The acknowledging of an elastic behavior during the return of the indentation procedure led to the mathematical approach and further development of methods to obtain the elastic moduli of the indented material.…”

The research interest in titanium alloys lies in the fact that their exceptional mechanical properties make them ideal for specific industrial applications, such as biomedical, aerospace, and military industries. [1][2][3] Despite its high cost, Ti-6Al-4V alloy is currently the most widely used titanium alloy, [4] combining good biocompatibility and corrosion resistance, [5][6][7][8][9][10] high strength, low weight, and ductility. [11][12][13][14][15][16] Several manufacturing processes among the aforementioned applications contemplate the implementation of material characterization procedures, either on pristine samples of the material or on previously manufactured parts. The most commonly applied experimental procedures to identify the macroscopic orthotropic elastoplastic properties of a material include monotonic tensile, [17,18] compression, [19,20] and shear [21,22] tests of material samples obtained from its orthogonal directions. The main limitations of these tests are the size of the specimens and their subsequent destruction,
