Dynamic tensile (micro-spallation) fracture and subsequent recompression in a molten state
is the key physical process for metallic materials undergoing multiple intense dynamic …

Spall strength characterizes the tensile performance of materials under high strain rates.
However, theoretical prediction of the spall strength has long been a big challenge since it …

This study investigated on the spalling behavior of single-crystal aluminum under uniaxial
impact loading at the micro-scale. Under the framework of non-equilibrium molecular …

Micro-spalling is a dynamic fragmentation process that is coupled with shock-induced
overheating and melting. It has been observed in series of shock experiments and in several …

The void coalescence under strong dynamic loading is a significant spallation process for
ductile metals. Since the spallation is basically dominated by tension waves, most void …

Together with void nucleation, growth, and coalescence, void collapse is a crucial
component in ductile spallation. This work reports single void collapse behaviors in perfect …

Micro-spallation in metals is a complex dynamic fragmentation process accompanied by
shock-induced overheating and melting. However, the damage evolution involved in this …

The shock responses of single crystalline aluminum under double decaying shock loadings
are systematically studied by atomistic simulations and theoretical models. Two successive …

The micro-damage mechanisms in ductile metals play a very important role in the spallation
process. Nonequilibrium molecular dynamics (NEMD) is used to examine the effect of …

Aluminum alloys undergoing deformation exhibit complex multi-type-void damage evolution
driven by microscale heterogeneous deformation; in return, the accumulated damage …
