Abstract

The weakening groove becomes the weaker link in separating unit since it bears axial load, bending moment and shearing force during operating. The strain distribution of weakening groove is obtained by ARAMIS system based on 3D digital speckle correlation method (DSCM). The result indicates that there is stress concentrate band in each groove, and the strain increased from the lower one to the upper ones. The result also demonstrates that the ARAMIS system performed with good results, especially in 3D deformation and stress concentrate measurement.
