• 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.
