根据能量法求出的非完美界面复合材料应变能表达式，定义了损伤界面能。分别计算了体变所引起的损伤界面能密度与夹杂内应变能密度的比值和畸变引起的两者比值．发现这两个比值正是文献[8]中所定义的两个无量纲因子αt和αG。这就为αk和αG赋与了新的物理含义，从而揭示了非完美界面复合材料定规模量随αk、αG增大而减小的物理本质，即损伤界面能越大刚度越小。文未给出了常见夹杂形状的αk、αG因子公式。
According to the expression of strain energy of imperfect interface composite calculated by energy method, the damage interface energy is defined. The ratios of the energy densities caused by bulk changes and the strain energy densities in the inclusions are calculated separately. The two ratios are found to be the two dimensionless factors αt and αG as defined in [8]. This imposes a new physical meaning on αk and αG, revealing the physical nature of the non-perfect interfacial composites decreasing in magnitude as αk and αG increase. That is, the greater the damage interface, the smaller the stiffness. The text does not give a common inclusion of αk, αG factor formula.
