The maximum values of the applied force and elongation of the structure under tensile tests are shown in Fig. 15. It is clear that the value of the parameters ‘a’ has a considerable influence on the strength and ductility of the repaired structure. The higher the value of the ‘a’ has increased the elongation and the maximum force of the structure therefore decreases a sudden rupture. Fig. 16 shows another change to the opposite of the one shown above, or we have reversed so that the fixed b value follows 50 mm and we have varied ’a’. The different values of the parameter 'a' in the corner of the patch were analyzed digitally in tensile order to estimate the influence of this parameter on the resistance of the structure. Fig.16a shows the tensile curves for the different values of ‘a’. It is clear that in the preceding example if ‘a’ increases the strength of the plate improves significantly.
