Calibrated radiometric light curves in three separate wavebands are presented for labscale hypervelocity impacts of an aluminum sphere onto aluminum targets conducted at Johns Hopkins University HyFIRE facility. The measured data is compared to synthetic light curves produced from a 3-D radiative transport software…
A combination of low density and high strength make boron carbide a desirable material for protection applications. However, the ballistic performance of hot-pressed boron carbide is affected by its susceptibility to amorphization beyond the Hugoniot elastic limit (HEL) and by the presence of processing-induced…
A multi-mechanism based constitutive model is presented for brittle ceramics subjected to projectile impact loading. The mechanisms considered as part of this model includes multi-scale fracture, an equation of state, granular flow, amorphization and pore-evolution. The multi-scale fracture is represented at the macroscale through…
The accelerating development of atmospheric hypersonic vehicles and the increasing utilization of orbital space—both environments in which very high velocity particle impacts are effectively guaranteed to occur—has only deepened the need for accurate mechanical understanding of the highly coupled multi-physical phenomena observed in hypervelocity…
