• Abstract:
  This paper describes engineering analyses of a railroad
  
  tank car impacted at its head by a rigid punch. This type of
  
  collision, referred to as a head impact, is examined using
  
  dynamic, nonlinear finite element analysis (FEA).
  
  Commercial software packages ABAQUS and LS-DYNA are
  
  used to carry out the nonlinear FEA. The sloshing response of
  
  fluid and coupled dynamic behavior between the fluid inside
  
  the tank car and the tank structure are characterized in the
  
  model using both Lagrangian and Eulerian mesh formulations.
  
  The analyses are applied to examine the structural behavior of
  
  railroad tank cars under a generalized head impact scenario.
  
  Structural behavior is calculated in terms of forces,
  
  deformations, and puncture resistance. Results from the two
  
  finite element codes are compared to verify this methodology
  
  for head impacts. In addition, FEA results are compared to
  
  those from a semi-empirical method.
