Analyses using ANSYS and LS-DYNA were performed to determine the response of MC-331 pressurized cargo tank heads when striking various obstacles. The incorporation of head shielding was shown to improve the crashworthiness for angled impacts into a wall or impact with a bridge support column. Only minor protection against normal (perpendicular) impacts into a rigid flat surface or rigid post is a realistic goal. Correlations to an accident that occurred in White Plains, NY were used to validate the finite element model. Additional correlations with drop tests and material characterizations tests were performed.
