Features 01
Expected Problems
Aren't you having these kinds of problems in press forming?
• Dimensional defects due to changes in the formed part shape after several days.
• Inadequate shape prediction accuracy of press-forming CAE.
• Shape changes between in-line inspection and shipping inspection.
Features 02
Technology highlight
• Shape changes occur in press-formed parts with the passage of time after die release (Fig.).
• FEM analysis can acquire the springback shape and residual stress immediately after die release.
• Sets stress conditions to relax/reduce residual stress by 5 % or more, and calculates the balance of moments of force by analysis.
• Contributes to improve dimensional accuracy predictions by enabling prediction of deformation due to time-dependent stress relaxation under condition without external loading.
