This work deals with the experimental measurement of full-field displacements and strains evaluation on the surface of flat high-ductile aluminum specimens in the vicinity of the V-notch during loading. Two different specimen geometry configurations, boundary and middle notch, are tested and compared in terms of deformation constraint. The enhanced Digital Image Correlation method in conjunction with strain gage measurement is employed for the precise full-field strain evaluation.
