The evaluation method is FLD (Forming Limit Diagram)! JSTAMP allows for analysis by inheriting the conditions from the previous process.
We will introduce a case study that examines the improvement of "cracks" and "wrinkles" by changing from single-stage to multi-stage press processing. In JSTAMP (Solver: LS-DYNA), it is possible to carry out analysis while inheriting the state of the previous process, allowing for the reproduction of multi-stage press processing. As a result, both the tendencies for cracks and wrinkles in the product parts were improved simultaneously as intended in the multi-stage processing. [Case Overview] ■ Analysis Model for Multi-Stage Processing - Stage 1: Punch stroke speed of 5000 mm/s, holder load of 20 kN - Stage 2: Die stroke speed of 10000 mm/s, holder load of 380 kN ■ Results - Both the tendencies for cracks and wrinkles in the product parts were improved simultaneously as intended. *For more details, please refer to the related links or feel free to contact us.
