The Effect of Transient Loading Discretization on a Rotating Disk Using Lawrence Livermore National Laboratories' Dyna 3-D

Abstract

A simple disk, representative of a simplied artillery round, was modeled. Several suboptimal modeling techniques were incorporated and compared against optimal modeling techniques to explore the errors introduced. The suboptimal model included wedge elements and an abrupt change in element density. The response to different contact algorithms was also investigated. In addition, the effect of various time steps of the loading curve was also investigated.
