Optical Forming Analysis


The forming analysis system ARGUS supports the optimization of the sheet metal forming process taking into account the correct material selection and the optimization of tools. This is a decisive factor for competitiveness, particularly in the automotive industry.

ARGUS provides full-field results with high local resolution for small as well as for large components. Therefore, it is ideal for numerous sheet metal forming tasks like: detection of critical deformation areas, solving complex forming problems, optimization of forming processes, verification of tools as well as verification and optimization of numerical simulations.


In addition, it provides full-field results for the verification of numerical forming simulations.

ARGUS takes up conventional and proven methods of the forming analysis, which are based on the structuring of the blank. The measuring system operates independently of the material. It can be used to analyze components made from flat blanks, tubes or other components manufactured by an internal high pressure forming process (IHPF).


All results are presented in a fine-resolution mesh created from the determination of the 3D coordinates and displaying the surface of the measured object. In the forming limit diagram, the measured deformations are compared to the material characteristics of the blank (forming limit curve).


The specimen is recorded by means of high-resolution images which are then evaluated using the ARGUS software. From the 3D coordinates of the object points, the actual results of the forming and the sheet metal thickness are calculated taking into account the component’s geometry and following the rules of the plasticity theory. First, the form changes are displayed in a false-color 3D mesh. Labels help to represent special points on the surface with their respective measuring values. In diagrams, any sections can be represented.
