ABSTRACT:
The mechanical properties within a part are determined as a function of depth in a non-destructive manner by punching the body with a series of punches having different radii of curvature. Using a plastic criterion with the data obtained the elastic limit of the body as a function of depth is determined as well as the residual self-stresses that exist in the part.
