Class 4 - Introduction to Crashworthiness


  • 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.
