Recycled rubber materials are one of cheap and suitable materials for energy absorbers in protective structures.
On the other hand, conceptual design focusing on overall concept of protection does not need precise and longtime lasting simulation but prefer time effective simplified simulation with trend of results for all main used materials.
The common feature for hyperelastic materials is fact, that typical compression is between 10 – 60% and the material curve for similar density materials does not differ significantly (see Fig. 1a).
