Benefits of this Project

In this project, you will analyse the head impact on the car hood. You will learn how to set-up the case study by giving the required geometry transformations, boundary conditions, material models, contact definitions. Stress, strain, head impact coefficient(HIC) values will be calculated and studied in post-processing.

What will you do in this project?

Step 1 - Geometry transformation and case set-up

Step 2 - Effective strain values calculation after the impact

Step 3 - Effective stress values calculation after the impact

Step 4 - HIC value and energy calculation through LS-PrePost

In this project, you will analyse the head impact on the car hood in LS-DYNA software,

  • Organise the multi include file model using the keywords *INCLUDE, *INCLUDE_TRANSFORMATION, *DEFINE_TRANSFORMATION
  • Set-up the case study by defining required boundary conditions, contact definitions, material models etc in LS-PrePost
  • Run the simulation by using a proper LS-DYNA keyword deck
  • Analysis of results like stress, strain, system energy through the post-processing
  • Calculation of head impact coefficient/criteria (HIC) through LS-PrePost

Pedestrain Head impact simulation using LS-DYNA

In this project, you will set up a case study for head impact simulation in LS-DYNA. Basically, you are supposed to replicate a scenario where the headform will impact the car hood. The headform and hood geometry are provided separately. These geometries should be organised by multiple include keywords. The headform is transformed to make an impact angle between 35-75 degrees and given fixed velocity.  Proper material models and contact definitions are chosen for the given geometries and relevant post-processing results are requested through LS-PrePost. The stress-strain plots, system energy and other global statistics are analysed through the results. Head injury criteria/coefficient (HIC) is also calculated through postprocessing tool LS-PrePost. Based on the HIC value and other results the severity of the impact is interpreted.
