Abstract:
Uvajanje novih visokotrdnostnih jeklenih pločevin v avtomobilsko industrijo postavlja orodjarstvo pred nove izzive. Višje trdnosti pločevin so običajno dosežene na račun zmanjšanja preoblikovalnosti in povečanja občutljivosti na elastično izravnavanje. V diplomski nalogi sem zato z vidika konstrukterja v orodjarni predstavil probleme načrtovanja orodja za materiale višjih trdnosti ter prikazal pomen računalniških simulacij pri napovedovanju obnašanja pločevine med in po preoblikovanju. Teoretičnim dejstvom sledi praktični primer, pri katerem je vidno dobro ujemanje realnega preoblikovanja z rezultati računalniških simulacij in omejena zanesljivost napovedovanja elastičnega izravnavanja.

Title:
NUMERICAL SIMULATIONS OF SHEET METAL FORMING FOR AHSS IN COLD
Abstract:
Introducing of new Advanced High Strength Steel (AHSS) into automotive industry presents new challenges for toolmaker companies. The higher values of strength are usually achieved at the expense of reduced formability and increased sensitivity of springback. The task of my diploma work is to show construction problems of tools for materials of higher strength and the importance of computer simulations in predicting the sheet metal behavior during and after forming. Theoretical facts are followed by a practical example, which has a good match with the results of the computer forming simulations and limited reliability of FEA springback prediction.
