Figure 5 shows analyses of displacement on the arc length of the spot laser. Figure 6 shows the calculation of stored energy density (N/m²) which is equal to 6 10 7 N/m² Figure 7 shows the calculation of the volumetric strain which is equal to 0.2, figure 8 shows the calculation of the volume: stress tensor, z component (N/m²). Which is equal to 6 10 8 N/m².
