Applied Forming Simulation with eta/DYNAFORM

This course provides an introduction to the simulation of sheet-metal and hydroforming processes with eta/DYNAFORM and LS-DYNA. All steps required to set up a LS-DYNA forming simulation are covered. The eta/DYNAFORM program is a special preprocessor for simulation of forming processes with LS-DYNA. The LS-PrePost program is presented for use in postprocessing.
