The XTDIC-FLC sheet metal forming limit measurement system continuously records the entire deformation of the sheet metal from the impact of the circular punch to failure in the hydraulic testing machine. Based on the sheet metal surface strain field, it determines and establishes a highly accurate FLC curve for the material.

The forming limit diagram (FLD) is an effective tool for evaluating the forming process and identifying cracking trends. Using our proprietary XTSM software, users can easily create FLDs, providing a technical foundation and practical criteria for evaluating sheet metal forming performance and improving forming processes.

The XTDIC-FLC sheet metal forming limit measurement system can intuitively display the location of sheet metal necking or fracture, output a forming limit diagram, and compare and verify it with finite element simulation to make the prediction results more accurate and optimize material development and process selection.
