Crash Analysis

The seminar session that was planned for October 25-28, 2021 is canceled due to the Swedish Government's extended entry ban, from countries outside and within the EU/EEA. Our lecturers, traveling from the United States, can at this point not enter Sweden.

Please be aware that this is a traditional seminar held at DYNAmore Nordics' office in Gothenburg. The seminar may be canceled depending on the status of the pandemic and Fohm's and WHO's recommendations, and that the required minimum number of entries to the seminar is fulfilled.

This is an advanced course and applies to engineers which have experience in the application of explicit programs or who 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 the 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 the 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: the 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 a 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.
