cross section crash boxes

4.5.2. Uniaxial Compression Testing of Empty Original Crash Boxes
The original empty crash boxes without trigger mechanism were compression
tested at a loading rate of 5 mm min -1 (Figure 4.12 (a)). Boxes with corrugation sections
were also tested under the same loading rate (Figure 4.12 (b)).

section.
4.5.3. Uniaxial Compression Testing of Empty and Partially Foam
Filled Crash Box without Montage Parts
Empty and partially foam filled 1050H14 aluminum crash boxes (Figure 4.13) with
trigger mechanism were tested at a deformation speed of 5 mm min -1 (6.65 x10 -4
These boxes were filled with Al foams (0.11 and 0.15 relative density) and tested at the
same deformation speed. Test sample coding and the number of compression tests are
tabulated in Table 4.1.
