Explizite FEM und transiente Analyse

What it is about

You learn the theory and application of the explicit finite element method (FEM) for transient analyses, including specialized modeling for impact and crash mechanics. In the end you will be able to understand explicit Updated-Lagrangian formulations, time stepping integration and contact algorithms and apply them to problem-related simulations.

What you will be able to do

• Reproduce essential aspects of the Updated Lagrangian FEM, time stepping integration and contact simulation
• Explain differences between implicit and explicit FEM
• Understand strain- and stress measures of continuum mechanics
• Apply mathematical methods of transient analysis
• Analyze numerical implementation aspects
• Evaluate technical literature
• Develop and apply models for transient simulation with explicit FEM

What the module consists of

• VorlesungDelivery of module topics using continuum mechanics and contact mechanics examples; discussion and motivation for independent literature work
• SeminarIn-depth discussion of related modeling and simulations (e.g. LS-DYNA, Python)

Teaching method
