| 摘 要： | 由于复合材料的引入,应该用“设计值”和“许用值”来代替“设计许用值”。讨论了设计值与许用值的关系,并指出复合材料结构压缩设计值主要取决于冲击损伤容限许用值。提出了应把冲击损伤破坏曲线定义为初步设计阶段用冲击损伤容限许用值,论证了这一定义的合理性,并给出了由该许用值确定压缩设计值的一般原则和过程。

| Abstract: | In this paper the authors proposed that the term of "design allowables" should be replaced by "design values" and "allowables" as composites were used in aircraft structures. The relationship between design values and allowables was discussed. The determination of compressive design values for composite structures was based mainly on impact damage tolerance allowables. The impact damage failure curve of typical laminates was defined as the impact damage tolerance allowable and the reasonableness of this definition was discussed. The principle and method for determining this allowable were proveded. The suggestion to develop the compressive design value for aircraft components based on this allowable was made as well. |
