The present disclosure involves a method for determining the critical local expansion of a component with an eye toward the appearance of edge cracks based on an expansion of the component in the shaping process. Given a local expansion of the component at the edges that is smaller than the critical local expansion, no edge cracks arise that are larger than 1 μm. In particular, at least one expansion test is performed with at least one test component, and a critical overall expansion is determined with the at least one expansion test. The local maximum expansion of the test component is determined that the test component exhibits at the time of the critical overall expansion of the test component, and the local maximum expansion is the critical local expansion.
