Recent Developments in JSTAMP/NV for the Best Stamping Simulation Environment

In recent years, expectations for stamping simulation systems have increased in stamping die design process, as the needs for lightweight products and short production lead time have grown. Aiming at the best stamping simulation environment, JSOL Corporation has been developing JSTAMP/NV since 1996. One of the most competitive advantages of JSTAMP/NV is accurate prediction of deformation and formability by explicit and implicit solutions in LS-DYNA®. JSTAMP/NV also incorporates the implicit solver JOH/NIKE and the one-step inverse solver HYSTAMP developed by JSOL Corporation. This integrated system has been enjoying a good reputation in stamping die industry, especially Japanese automotive, appliance, and electronics manufactures and their suppliers. The recent needs towards stamping simulation software can be classified as: accurate results and their evaluation, short computation times, easy-to-use features for iterative process improvement, and support for modern stamping technologies. JSTAMP/NV continues to evolve to meet such requirements. In this paper, we present the recent developments in JSTAMP/NV, including ironing analysis support using solid elements, Yoshida-Uemori model material database, advanced trimmed mesh, enhanced springback compensation, easy-to-start reanalysis feature, free 3D viewer for collaboration, and hot stamping analysis capability.
