Abstract

The J. N. Johnson void growth fracture model has been implemented into Magi to develop a capability to predict orbital debris generated from hypervelocity impacts or programmed explosions. Magi is a hydrodynamic code based on Smoothed Particle Hydrodynamics (SPH). This paper demonstrates advances in modeling fragmentation by calculating the debris environment generated from aluminum spheres impacting thin aluminum sheets representing debris shields. The shape of the debris cloud, fragment size, and fragment velocities are compared to the experimental work documented by Piekutowski. Plots of fragment mass versus cumulative number of fragments are also presented. Calculations of flyer plate experiments are presented and discussed to provide a foundation for understanding the fracture model and its input parameters. The results show that SPH is quite natural for modeling the fragmentation for these experiments.
