    • A system and method for predicting structural failure of a wall of a fluid containment vessel, such as a hydraulic hose or other type of pressurized conduit of types used in mobile machinery, automotive, aerospace, manufacturing, and process equipment. The wall of the vessel has an innermost layer for contact with the fluid contained by the vessel, and an outermost layer parallel with the innermost layer. The system includes strain-sensing means between the innermost and outermost layers and comprising at least one conductor parallel to the innermost layer of the wall. The system and method entail sensing changes in an electrical property associated with the at least one conductor resulting from distortion of the wall of the vessel causing distortion of the at least one conductor.
    • 用于预测流体容纳容器的壁的结构故障的系统和方法,例如在移动机械,汽车,航空航天,制造和加工设备中使用的类型的液压软管或其它类型的加压导管。 容器的壁具有与容器所包含的流体接触的最内层,以及与最内层平行的最外层。 该系统包括在最内层和最外层之间的应变感测装置,并且包括平行于壁的最内层的至少一个导体。 该系统和方法需要检测由至少一个导体变形引起的容器壁变形引起的与至少一个导体相关联的电气特性的变化。
