Forming limit diagrams (FLD) are used to determine process limitations in sheet metal forming, i.e. as a level of formability assisting in the estimation of stamping characteristics. This paper deals with the experimental determination of a forming limit curve (FLC) using the Erichsen test. In this case, FLC of an austenitic stainless
steel X5CrNi18-10 is obtained by performing the Erichsen test with different shapes of specimens. Furthermore, utilization of FLD for evaluation of a hydroforming process is shown in the second part of the paper.
