*3.2.1 Quasi-static tests*

Quasi-static tests are performed to failure, under the three deformation rates specified (0.001, 0.01, and 0.1 s<sup>−</sup><sup>1</sup> ). **Figure 15** shows stress-strain curves obtained for each strain rate applied, while **Table 5** summarizes the post-processed results. Sample S1 for 0.001 s<sup>−</sup><sup>1</sup> tests was discarded due to reload during the test. The average value obtained for the peak stress for the quasi-static regime is 358.295 MPa with a coefficient of variation (CV) of 5.235%, which means that it is constant. Strain at peak stress and modulus presents the same behavior with values as of 1.676%–(CV) 8.875% and 21.999 GPa–(CV) 2.623%, respectively. Due to this it is said that mechanical behavior remains constant in quasi-static regime.
