Advanced Implicit Analysis in LS-DYNA

 

LS-DYNA, the state-of-the-art explicit finite element (FE) program for large deformation mechanics, has also extensive capabilities for solving implicit type of problems. This course presents a theoretical and practical introduction to the implicit capabilities in LS-DYNA with a focus on structural analysis. The course is suited for users with at least some previous experience from using LS-DYNA for explicit analyses or for experienced users of other implicit FE-programs.

Course outline:

  • Linear and non-linear static analysis
  • Modal analysis and linear dynamics by modal superposition
  • Implicit non-linear dynamics
  • Eigenvalue buckling analyses
  • Nonlinear buckiling and post-buckling analysis using the arc-length method
  • 2D, 3D and axi-symmetric models
  • Elements for implicit analysis
  • Material models
  • Loads, boundary conditions and constraints
  • Contact definitions, tips and tricks
  • Troubleshooting convergence problems
  • Control parameters
  • Output format and output files
  • Pre and post processing with LS-PrePost
  • Selected exercises throughout the course
