Auxetic foams have gained popularity within the research community because of their enhanced properties, such as low density combined with high relative stiffness, toughness, and damping properties. Low polystyrene (PS) are commonly used in packaging industry, but a short service life generate volume waste (white pollution). This is why recycling valorizing necessary imperative. The objective t...

With their increased energy absorption capacity, auxetic materials are perfectly fit to develop new, enhanced lightweight crash absorbers for cars. Herein, the mass distribution along struts is optimized via finite element analysis with a parameterized optimization. Four different unit cells taken from literature and parameterize, models simulate, specific capacity optimizes. The two highest th...
