Mechanical Analysis and Multi-Objective Optimization of Origami-Inspired Tree-Shaped Thin-Walled Structures Under Axial Impacts.

As shown in Figure 4 a, as θ increases, the IPCF exhibits a monotonically decreasing trend, while the rate of change in IPCF shows a decreasing trend; as θ increases, the SEA exhibits a fluctuating trend and lacks monotonicity, reaching a minimum value at θ = 100° and a maximum value at θ = 70°; As θ increases, ULC first decreases and then increases, reaching a minimum at θ = 70° and a maximum at θ = 120°.
