In the following tables (Table 2, 3 and 4) are captured all the data obtain through two of the selected methods. Digital Image Correlation (DIC) and numerical analysis have provided information about the displacements that occurred at each node, organized by rows (denoted by first digit) and columns (denoted by second digit). From the experimental testing can be exposed only the direct displacement of the entire structure. The experimental tests primarily established the baseline for the displacement all over the structures and served as a reference in comparison with the other methods. For Sample M1X1 through experimental testing has been obtained a maximum displacement of 5.23 mm, which closely aligns with the values generated through DIC (5.249 mm) and numerical analysis (5.12 mm). The same trend is observed for sample M3X1, where the direct displacement obtained through conventional compression testing is 6.13 mm, and for sample M3X3 the amount of 10.98 mm. The comparison purpose is to demonstrate that the discrepancies in the data obtained are minimal, under 5% for the majority of the data points. This validates the results obtained through all three methods as complementary and consistent with each other.
