Plane-wave shock deformation has been shown to produce deformation twins or twin-faults
in essentially all metal and alloys. In FCC metals and alloys twinning depends upon stacking …

Shaped charge jet and slug formation is characterized prominently by dynamic
recrystallization which may occur in deformation-recrystallization cycles, providing a …

High-purity copper rods in a range of grain sizes—29 μm, 141 μm and 375 μm—were shock
loaded in an cylique, cylindrical shock fixture which simultaneously and linearly strained the …

Normal incidence impact craters in thick 6061-T6 aluminum targets formed by spherical
soda-lime glass projectiles at velocities ranging from 1.7 km s− 1 to 5.2 km s− 1 were …

Deformation microtwins characteristic of Neumann bands dominate the residual
microstructures beyond a dynamic recrystallization and highly deformed regime below the …

A systematic study of microbands formed in polycrystalline and single crystal copper
samples after loading by spherically converging shock waves with different initial amplitudes …

In this study, we have observed dense Neumann bands in the central region of the head of
an iron explosively formed projectile (EFP) and provided unambiguous TEM evidence that …

The literature concerning the behaviour of metals at strain rates from quasi-static to ultrahigh
is reviewed. Deformation mechanisms that are operative include twinning and adiabatic …

We performed hypervelocity impact experiments on SS400 steel with a polycarbonate
projectile at velocities up to 9 km/s. Spall fracture damages were observed near a rear …

In recent studies of impact cratering in copper targets, we have, along with other researchers
in our laboratory and other colleagues elsewhere, made some rather startling observations …
