• Abstract:
  This paper describes analyses of a railroad tank car
  
  impacted at its side by a ram car with a rigid punch. This
  
  generalized collision, referred to as a shell impact, is examined
  
  using nonlinear finite element analysis (FEA) and threedimensional
  
  (3-D) collision dynamics modeling. Moreover, the
  
  analysis results are compared to full-scale test data to validate
  
  the models. Commercial software packages are used to carry
  
  out the nonlinear FEA (ABAQUS and LS-DYNA) and the 3-D
  
  collision dynamics analysis (ADAMS). Model results from the
  
  two finite element codes are compared to verify the analysis
  
  methodology. Results from static, nonlinear FEA are compared
  
  to closed-form solutions based on rigid-plastic collapse for
  
  additional verification of the analysis. Results from dynamic,
  
  nonlinear FEA are compared to data obtained from full-scale
  
  tests to validate the analysis. The collision dynamics model is
  
  calibrated using test data. While the nonlinear FEA requires
  
  high computational times, the collision dynamics model
  
  calculates gross behavior of the colliding cars in times that are
  
  several orders of magnitude less than the FEA models.
