Damage mechanisms and non-destructive test methods Toolkit

This knowledge base provides engineering personnel with comprehensive information, helping them to identify specific damage mechanisms common to a variety of industries and select the most appropriate Non-Destructive Testing (NDT) methods for inspection.

The information for each damage mechanism and NDT method is provided in set formats. This standard format facilitates use of the information in the development of inspection programmes, fitness-for-service (FFS) assessment and risk based inspection (RBI) applications.

Non-Destructive Test Methods

The NDT techniques described in this knowledge base have been split into the following categories:

  • Magnetic methods
  • Penetrant testing
  • Radiography
  • Eddy current
  • Ultrasonics
  • Visual

Damage Mechanisms

These have been split into three categories:

  1. Metal loss
  2. Environmental Damage
  3. Metallurgical and Mechanical Damage
Each damage mechanism page gives details of:

  • Susceptible materials
  • Environmental conditions
  • Expected failure mode
  • Description of damage
  • Methods of avoidance
  • Further reading
