METHOD FOR DETECTING SEPARATION IN A STRUCTURE

摘要

A method (100) for detecting separation in a structure (10) that comprises at least two portions or layers (12, 14) affixed together comprises forming a cavity (16) into the structure that passes through an interface formed between the two portions (12) and (14) and plumbing the cavity to a monitoring system. A pressure differential is established between the cavity and a reference pressure to which the structure (10) is exposed. A monitoring system monitors for a change in the pressure state of the cavity. Changes in the pressure state are indicative of a separation between the portions or layers (12) and (14).
