Analysis and Comparison of 2D Shell Elements in a Crash Tube with and without recommended Shell formulation property in Radioss. 

  OBJECTIVE Performing Frontal crash analysis of a car PROCEDURE 1. The unit system in place is [Kg mm ms]. Open the 0000.rad file in notepad and one can observe the unit system in the starter file.  2. Open the file in the hypercrash and import the neon_front_0000.rad file. Keep the preferred unit option as…
