Abstract

The work presented in this paper consists of a parametric study of explosively driven fracture and fragmentation of steel cylinders. The effect of cylinder height to wall thickness ratio on the failure mode and fragment shape is studied using a numerical model based on the meshless Smoothed Particle Hydrodynamics (SPH) method. The simulation results are supplemented with experiments with identical charge geometries and materials, to analyse the natural fragmentation behaviour of the different cylinders. Characteristic fragments were softly recovered in a water basin and fragment mass distributions are compared to the simulation results.
