Specific Energy Absorption (SEA): Definition, Importance, and Applications

Specific Energy Absorption (SEA) refers to the amount of energy a material absorbs per unit mass under specific conditions. It is a vital material parameter frequently used to evaluate a material's performance during collisions or impacts. In the automotive industry, SEA is a key indicator for assessing vehicle safety. Materials with high SEA values can effectively absorb impact energy, minimizing injury to occupants in accidents. Therefore, SEA is a significant concept in material engineering and the automotive industry.
