The Figure 6 shows the evolution of the strain fields in the x direction along two horizontal lines defined by points (Figure 5): (a) P 1 − P 3 , (b) P 4 − P 6 . The line defined by P 1 − P 3 points is at a height of y = 23 mm and the line defined by P 4 − P 6 points is at a height of y = 3 mm. It is possible to observe that the strain in the higher horizontal line of P 1 − P 3 points presents more stable values than in the lower horizontal line of P 4 − P 6 points, which shows oscillations.

Evolution of the strain fields ε xx (mm / mm) along three vertical lines defined by: (a) P1-P4 ( x = 7 mm), (c) P2-P5 ( x = 69 mm) and (e) P3-P6 ( x = 130 mm), and evolution of the strain fields ε yy along three vertical lines defined by: (b) P1-P4 ( x = 7 mm), (d) P2-P5 ( x = 69 mm) and (f) P3-P6 ( x = 130 mm), at di ff erent stages (87 s, 145 s, 290 s and 406 s). The Figure 7 shows the evolution of the strain field in the y direction along two horizontal lines defined by points (Figure 5): (a) P 1 − P 3 and (b) P 4 − P 6 points, respectively. It can be concluded that there are more stable values in the strains in the upper path (line P 1 − P 3 ) than in the horizontal line of P 4 − P 6 points. The Figure 8 presents the evolution of the strain field in the x and y directions along three vertical lines defined by (Figure 5): (a) P 1 − P 4 ( x = 7 mm), (b) P 2 − P 5 ( x = 69 mm) and by P 3 − P 6 ( x = 130 mm). The maps (a), (c) and (e) demonstrate the strains in the x direction on the three vertical lines. It can be concluded that the strain in this direction
