Material tests on all major foams and rubber like materials have been performed. The specimens were taken from blocks provided by Denton COE in Heidelberg. The blocks are depicted below.
The following materials were tested:
The tests were adapted to derive material data for *MAT_FU_CHANG_FOAM and *MAT_SIMPLIFIED_RUBBER. Hence, the emphasis was on static and dynamic tension and compression tests. For the rubber like materials, the compression tests were also performed with a lateral obstructed expansion. The used strain rates were:
| Test | Type | Strain rate | Lateral expansion |
|---|---|---|---|
| 1 | Tension | 0.001 1/s(static) | free |
| 2 | Tension | 0.1 1/s | free |
| 3 | Tension | 10 1/s | free |
| 4 | Tension | 100 1/s | free |
| 5 | Tension | 500 1/s | free |
| 6 | Compression | 0.001 1/s(static) | obstructed |
| 7 | Compression | 0.001 1/s(static) | free |
| 8 | Compression | 0.1 1/s | free |
| 9 | Compression | 10 1/s | free |
| 10 | Compression | 100 1/s | free |
| 11 | Compression | 500 1/s | free |
