Full-field 3D forming analysis reveals for-ming-dependent material defects before they are visible to the human eye. in the for-ming limit diagram, measured form changes are compared to the material characteristics of the blank (forming limit curve) and critical deformation areas are detected. in addition, previously simulated geometry and strain are compared full-field and numerically with real measurements of the part.
