Development of Analytical Tools for the Punch Investigation of the Transuranic Package Transporter (TRUPACT)

摘要

Methods of simplified analysis are presented for the evaluation of the punch resistance of the TRUPACT sidewalls. The first method consists of an elastic analysis of a foam-backed triangular plate. This analysis, which accurately models the geometry of the TRUPACT sidewall (though not the material behavior) is then used to evaluate the influence of the particular location on the sidewall where the punching is taking place. The second method consists of a plastic membrane analysis of a circular plate in which both the plate material and foam backing exhibit plastic behavior. In this analysis, the material behavior of the TRUPACT is accurately modeled, whereas the geometry is not. This analysis is used to estimate the minimum thickness of the foam-backed outer skin required to prevent its perforation. (ERA citation 06:035321)
