Metal Forming
The two-day course communicates the fundamentals of the simulation of sheet-metal forming processes with the LS-DYNA program and provides notes and hints for everyday practical application. Particular attention will be given to the forming-specific settings and features in LS-DYNA.
The focus of the first day is primarily on introductory remarks about forming simulation in LS-DYNA. Required input decks, settings, interrelationships and procedures will be explained in detail. Another focus will be the critical consideration and examination of the simulation results and possibilities to overcome problems by means of alternative approaches and methods.
The goal of the seminar is to enable the user to independently select the correct settings and parameters for a specific task. On the second day, the understanding of the fundamental theory imparted will be deepened, and its limits will be discussed.
This seminar is suitable for users from the area of metal forming who wish to learn how to use LS-DYNA for simulation of sheet-metal forming processes or who wish to deepen existing knowledge.
