Figure 4.65 presents the distributions <strong>of</strong> surface permanent deformations at different<br />
distances <strong>to</strong> the center when the permanent deformation at the center was 25 mm It is shown that<br />
all test sections had similar distributions, i.e., the permanent deformation decreased with an<br />
increase <strong>of</strong> the distance.<br />
