damage the structure. The angle of the elbow changes the shape not only of the elbow itself but also of the overall structure which is stressed in these different modes of flexion that of opening, closing and out of planes. Under a pressure of 30bar and at the same temperature of 40 ° C, the angle effect of the elbow is well presented in the structural response up to their damage and under different bending modes.

Figure 8: tangential stress just before damage with effect of angular elbows in the case of temperature 40°C and pressure of 30 bar under opening, closing and hors plans flexion moment.
