Metal foams were excellent impactenergyabsorption material.
泡沫金属是一种优良的冲击吸能材料。

They are mainly concerned with the tensile and compressive behavior, energyabsorption, dynamic impact, failure criterion and constitutive relation, creep, fatigue and fracture of these materials.
The front and rear underrun protections can effectively protect passenger cars from inserting under trucks, rational energyabsorption characteristics can improve impact compatibility.
