In this paper, a three dimensional crack identification method is presented.
optimisation process is described and potential analysis is carried out with use of the
Dual Boundary Element Method (DEEM).
Design sensitivites are computed with
a new derivative Dual Boundary Element formulation.
An example is presented to
demonstrate the efficiency of the proposed method together with a comparison of
various optimisation methods.
Non-Destructive Testing (NDT) of components in industry is often used to detect cracks
and determine their effect on the component's life span.
Components found to contain
insignificant cracks may be allowed to continue in use, whilst others with larger cracks are
