Introduction to Explicit Dynamics with Workbench LS-DYNA

Intro to Explicit Dynamics with Workbench LS-DYNA

Course Objectives

This seminar provides an introduction into explicit transient simulation with Workbench LS-DYNA. It is designed for simulation engineers, who would like to use LS-DYNA for the analysis of non-linear, dynamic problems: crash, impact, drop test, limit load analysis and metal forming. Besides providing the theoretical foundation for explicit dynamic analysis, and teaching the workflow around Workbench LS-DYNA, the acquired knowledge is strengthened by individual training and completion of practical examples.

Introduction to LS-DYNA and its workflow

  • Typical application areas for LS-DYNA
  • Integration of LS-DYNA into ANSYS Workbench: ANSYS Workbench LS-DYNA
  • Basics of LS-DYNA: explicit vs. implicit time integration and consequences
  • Stability of time integration method and control of time step size, mass scaling

Aspects of FE-Modelling

  • Basics of the FEM-Discretisation for LS-DYNA and fundamental meshing rules
  • Available finite element formulations (element integration, hourglass forms)
  • Modelling in Workbench LS-DYNA
  • LS-DYNA Keyword format
  • Model editing in LS-PREPOST

Execution of simulation

  • Influences on simulation speed and accuracy
  • Analysis settings
  • Control of output data; available result files

Evaluation of simulation results

  • Post-processing in ANSYS Workbench LS-DYNA and LS-PREPOST
  • Generation of contour plots and animations
  • Generation of time history plots

Modification and completion of exercises

  • Workbench LS-DYNA examples for dynamic and quasistatic analysis
