Study on Concrete Pier Impact Performance after Implementing Equal Cross-Section Stainless Steel with Protection from Closed-Cell Aluminum Foam

Figure 16

Fitting of the stress and impact velocity values of the No. 4 reinforcements. In the figure, diameter 16 is 50 mm closed-cell aluminum foam and diameter 20 is 100 mm closed-cell aluminum foam; when the Z2-16 reinforcement reached the yield stage at 1.2 m/s, its elastic modulus could not be determined, and only the first two three values were removed.
