Crash Analysis

Due to the corona virus and thus an increased risk that our lecturers are quarantined when returning to the US, we have decided to cancel the course this spring. The seminar will be re-scheduled in Sweden during the fall.



This is an advanced course and applies to engineers which have experience in application of explicit programs or which bring along experience from the field of dynamic and nonlinear calculation with implicit programs. The aim of the course is to show how to perform a crashworthiness simulation in the automobile industry using LS-DYNA, whereby the presented methods are transferable to other kinds of crashworthiness simulations (rail vehicles, components of vehicles, airplanes, vans, etc.).

As participants of this course we expect new fellow employees from the department of crash simulation of a car manufacturer, new fellow employees of suppliers in automobile industry (suppliers of components, engineering companies) or users in related industrial sectors.

Each crashworthiness simulation is a compromise between profitability and accuracy. At the moment there is no kind of a guideline for modeling and calculating crash. Therefore the user has to be aware of advantages and disadvantages of different kinds of modeling procedures depending on the purpose of the simulation.

Particularly the aim of the course is to show how to perform an accurate and reliable crashworthiness simulation by thorough modeling and further understanding of the procedure.


  • Introduction to crash simulation using LS-DYNA, history, possibilities, technical limits, accuracy and reliability problems, future developments
  • Modeling techniques for parts of car bodies: mesh-outlay, element quality, flanges and weld spots, contacts, etc.
  • Modeling techniques for components consisting of other materials than steel: motion of motor, tires, bolts, rubber buffer, etc.
  • Selection and description of suitable material models in crashworthiness simulation for soft foams (chair cushions), EA-Foams, rubber, etc.
  • Modeling of dummies with determination of material parameters
  • Airbag simulation, reference geometries, folded airbags
  • Modeling of barriers under extreme deformation
  • User subroutines
  • Quality control of models as well as analysis and evaluation of the results

The course instructor is an expert in crashworthiness simulation and is working for several car manufacturers using different FE-codes worldwide. He is also an excellent and popular teacher.
