Class 4 - Introduction to Crashworthiness
Format:
- 3 days
- Instructor lead or seminar
- Theory and hands-on exercises (using HyperWorks or LS-Dyna)
Content and Target Audience:
This course is an advanced level course targeted at those people who will be involved with performing or interpreting vehicle crash simulations on a day-to-day basis. Students should have an excellent understanding of explicit finite element simulation methods and also a good understanding of the goals of crashworthiness. By the end of the course the student will understand how to build crash models, identify important components and plan a crash analysis program. The course is based on implicit solutions and can be presented using either LS-Dyna or RADIOSS.
Prerequisites:
Prior FEA experience including building models (preferably in HyperMesh)
Topics:
- Introduction to crashworthiness theory and simulation
- Background theory to crash simulation
- Control cards for LS-Dyna
- Elements and materials
- Set-up loads and boundary conditions
- Making connections
- Contact basics
- Set-up outputs and control cards
- Mass-scaling and time-step stability
- Post-processing crash and other nonlinear explicit results
- Reviewing, understanding and presenting results
