摘要：

Digital Holographic Interferometry is considered for non-destructive testing of three-layered hollow structures produced by the pressure welding combined with the superplastic forming. Dispacement fields in the structure were calculated with the use of the finite element method for different schemes of fixing and loading within the elastic range. It is demonstrated that internal pressure loading of the structure fixed along the whole contour is a suitable scheme for detection of such defects as splits or fracture of stiffening ribs.
