Intelligent monitoring of jack-arch structures: the results of a preliminary study
  In this TRL study, a cast iron beam, instrumented with deflection gauges, strain gauges and two acoustic monitoring systems, was subjected to a series of load cycles. The aim of the test programme was to determine whether acoustic emission (AE) techniques could be used to form the basis of an intelligent monitoring system. The results support the view that AE was generated by a load-related mechanism - most likely due to micro-cracking of the cast iron - and so AE techniques might indeed form the basis of a monitoring system, but further work is required to develop a practical system.

Other similar contents:

The similarity algorithm calculates how much two contents in the system are similar to one another. So far, similarity is calculated based on similarity of the project type, area of interest and user type. Generally, if two contents have more parameters in common they are more similar to each another. More information.
