多孔材料在热击波压实下的本构方程

Development Status of Ocean Military Fiber Optic Cables in Some Foreign Countries

通过引入描述多孔材料中非零压状态基体体积占有比的承压系数αｖ，取代过去常用的多孔度α，对多孔材料的本构方程进行修正而得到ｐ＝αｖＦ（αｖ，Ｅ），解决了多孔材料发生熔化时，本构方程不适用的问题。应用结果表明，这种修正是合理的和可行的。

As one of the main fiber optic components, fiber optic cable has emerged many different designs in order to meet the needs for diverse military applications. This paper is the continuation of the paper “Development Status of Land Military Fiber Optic Cables in Some Foreign Countries”,concentrating on introducing the state of the art of ocean military fiber optic cables in some foreign countries.
