The XTOP3D XTDIC-FLC sheet metal forming limit measurement system utilizes Digital Image Correlation (DIC) technology to provide non-contact, full-field, high-precision, and visual measurements. It enables the rapid and accurate determination of Forming Limit Curves (FLCs) and allows for the observation of material flow, strain evolution, and defect initiation (such as necking, wrinkling, and fracture) during the sheet metal stamping process. This system facilitates the analysis of material forming behavior, precise failure prediction, and the optimization of stamping process parameters.

XTOP3D's independently developed XTDIC three-dimensional full-field strain measurement system can obtain the ultimate strain under different strain paths through computational analysis, thereby producing a complete forming limit FLC curve, clearly and intuitively judging whether there is excessive deformation in the part area, and providing data support for optimizing the forming process and verifying the simulation.

The XTOP3D XTDIC-FLC three-dimensional sheet metal forming limit measurement system, combined with a sheet metal forming test device, can quickly complete the surface strain distribution of thin-walled specimens throughout the forming process, analyze two sets of data: primary strain and secondary strain, and perform quadratic curve fitting on each set of data. The fitting points can be used to output FLC curve data.

The XTDIC-FLC sheet metal forming limit measurement system is used to introduce the sheet metal forming limit measurement process. In conjunction with the sheet metal forming and cupping test machine, it sprays disordered speckles on the specimen to collect sequential video images of sheet metal deformation during the cupping test. Based on grid strain analysis, digital image correlation measurement and other technologies, the limit strain is directly obtained, and the forming limit curve FLC is generated to establish a forming limit diagram.
