The material should be stiff, tough or Young modulus should be more or which property should be significant for excellent energy absorption?
Dear Hassan,
Sorbothane® absorbs up to 94.7% of impact shock. It is is a highly-damped, visco-elastic, polymeric solid. Sorbothane® “flows” like a liquid under load and is a thermoset, polyether based polyurethane that combines high energy absorption with near faultless memory. It is is the most efficient energy absorbing material on the market, hence—it is the best shock absorption material available today.
The researchers devised cell geometry capable of elastic buckling, giving NS honeycomb structures the resilience to recover their energy-absorbing shape and properties after impact. The cell dimensions can be customized to withstand different amounts of force, translating to a variety of versatile applications.
Hope it help you out.

Dear Hassan,
Sorry for last answer.
If question asked for which material property absorbs more energy or more impact absorption , answer among the three option you have supplied Indeed it is a toughness.
But if ask for mechanical property which is most impact absorbent for high yield materials..
Than my answer is resilience.
Hope it work out for you.

Thank you Ashish and Alpesh. The toughness and resilience are calculated when tensile load is applied. Will a material absorb same energy when a impact load is applied such as bullet fired on the material front face?
