WebJan 8, 2024 · As seen, addition of foam to rubber leads to an improvement in the energy absorption behavior of the hybrid since the area under the stress–strain curve is a direct measure of the energy absorbed during deformation. Simulation results are not available up to higher values of strain due to system computational power limitations. Fig. 6 WebMar 6, 2024 · The energy absorption and impact attenuation of low density polyurea (PU) foams (140–220 kg/m 3) is presented. The stress–strain behavior, energy absorption, cushioning efficiency, and energy return (resilience) are measured at a quasi-static strain rate using an Instron load frame. syscaem consultores
