Response of a stainless steel cylinder with elliptical ends subjected to an off-center blast load

PDF Version Also Available for Download.

Description

The response of a stainless steel cylindrical vessel with asymmetric internal blast loading is investigated by experiments, computations, and analysis. Previous research has focused on the response of cylindrical vessels for a centrally located charge. The vessel`s geometry consists of a thin shell cylinder with 2:1 elliptical ends. The high explosive charge is located on the vessel`s axis of symmetry and is axially offset from its geometric center. All explosives are spherical in shape and centrally initiated inside the vessel. The vessel holds the high explosive in air at ambient temperature and pressure. Two-dimensional, Eulerian finite difference calculations from a ... continued below

Description

The response of a stainless steel cylindrical vessel with asymmetric internal blast loading is investigated by experiments, computations, and analysis. Previous research has focused on the response of cylindrical vessels for a centrally located charge. The vessel`s geometry consists of a thin shell cylinder with 2:1 elliptical ends. The high explosive charge is located on the vessel`s axis of symmetry and is axially offset from its geometric center. All explosives are spherical in shape and centrally initiated inside the vessel. The vessel holds the high explosive in air at ambient temperature and pressure. Two-dimensional, Eulerian finite difference calculations from a hydrodynamic code (MESA-2D) are used to study the blast phenomenon and pressure loading on the vessel walls. The loading pulse is compared to data obtained from four experiments where several pressure transducers are positioned along the vessel`s circumference. The calculated two-dimensional loading is applied to a three-dimensional explicit finite element model (DYNA-3D) to predict the structural response of the vessel. The vessel`s structural response from the experimental wave interaction is recorded using strain gages, positioned along its circumference, and then compared with the finite element calculations. These results (experimental and computational) are then compared with analytical predictions and prove to correlate well at distances away from the ends. Experimental and computational results compare well at all other locations.
