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

Figure 10

Time history curve of the impact forces when the drop hammer was lifted to 4 m and 10 m, respectively. In the figure, diameter 16 is 50 mm closed-cell aluminum foam, and diameter 20 is 100 mm closed-cell aluminum foam.
