Content:
The representation of real-world processes and states, as well as complete process chains, using computer-aided tools has become indispensable in Mechanical Engineering. This can significantly enhance our understanding of processes, particularly in the fields of metal forming, joining technologies and component testing, whilst reducing the scope of time-consuming, experiment-based testing. The determination of characteristic values, which serve as input parameters for simulation, remains essential despite all technological progress. In the three aforementioned fields of application, the LS-Dyna software, together with its add-on tools, has also become established within industry. This class covers the fundamentals of experimental parameter determination as well as methods for modelling and calculation in LS-Dyna. The course is structured in two parts.
In the first part of the course, an introduction is first given to the basic functionality of LS-Dyna and the structure of the user interface (e.g. LS-PrePost). Subsequently, various aspects of the software that are significant in the field of metal forming are covered in depth. The first part concludes with numerically modelled application examples from the chosen specialisation, which are validated on a random basis against experimental data.
In the second part, the knowledge gained previously is applied to joining technology and component testing. To this end, the determination of the parameters required for the simulation (e.g. tensile specimens, LWF-KS-2 specimens) is first discussed, and the input parameters for the simulation section are derived from experimental data. A component-like model is then constructed, a load is defined, and a corresponding examination is simulated. Finally, the results and the insights gained are evaluated in terms of their plausibility.
