Abstract:
A method for detecting separation in a structure that comprises at least two portions or layers affixed together comprises forming a cavity into the structure that passes through an interface formed between the two portions and plumbing the cavity to a monitoring system. A pressure differential is established between the cavity and a reference pressure to which the structure 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.
