Abstract: | The paper describes a hybrid experimental and numerical method of Moiré Interferometry and the boundary-integral-element method.
The interference patterns used for the evaluation of the displacement vector are obtained by Moiré Interferometry. The boundary
displacements obtained experimentally are conveniently used for the calculation of the stress intensity factor in the body
by the boundary-integral-method. Some examples bear witness to the effectiveness and accuracy of the hybrid technique.
