Abstract:

The purpose of this study is to report two types of numerical experiments. First, a structural problem was modeled using the ABAQUSExplicit, DYNA3D, and DYSMASL computer programs. The problem consisted of the classic problem of Witmer i.e., an explosive detasheet was tested on a cylindrical panel and the permanent set deflection was measured and compared with the three numerical predictions. Secondly, the problem of a water column impacting on a series of flat or curved, rigid or flexible panels was modeled using the DYNA3D computer program. Due to the lack of experiniental data, the calculations were compared to limited Eulerian computer program CTH results. Finite element analysis, Cylindrical shell, Water slug.
