Development of JSTAMP‐Works/NV and HYSTAMP for Multipurpose Multistage Sheet Metal Forming Simulation
- Conference date: 15-19 August 2005
- Location: Detroit, Michigan (USA)
Since 1996, Japan Research Institute Limited (JRI) has been providing a sheet metal forming simulation system called JSTAMP‐Works packaged the FEM solvers of LS‐DYNA and JOH/NIKE, which might be the first multistage system at that time and has been enjoying good reputation among users in Japan. To match the recent needs, “faster, more accurate and easier”, of process designers and CAE engineers, a new metal forming simulation system JSTAMP‐Works/NV is developed. The JSTAMP‐Works/NV packaged the automatic healing function of CAD and had much more new capabilities such as prediction of 3D trimming lines for flanging or hemming, remote control of solver execution for multi‐stage forming processes and shape evaluation between FEM and CAD.
On the other way, a multi‐stage multi‐purpose inverse FEM solver HYSTAMP is developed and will be soon put into market, which is approved to be very fast, quite accurate and robust.
Lastly, authors will give some application examples of user defined ductile damage subroutine in LS‐DYNA for the estimation of material failure and springback in metal forming simulation.
