Local Thickening and Friction Reducing to Constant Resistance in a Prefolded Energy Absorption Device

Table 1

Variance results of the load-displacement curve of the device with different thicknesses.

Thickening height	14 mm	28 mm	42 mm	56 mm	70 mm
Variance	2.57 × 10^5	1.84 × 10^5	1.15 × 10^5	2.16 × 10^5	4.07 × 10^5
