A new scientific frontier opened in 2009 with the start of operations of the world's first x-ray
free-electron laser (FEL), the Linac Coherent Light Source (LCLS), at SLAC National …

The high strain rate dependence of the flow stress of metals and alloys is described from a
dislocation mechanics viewpoint over a range beginning from conventional …

In this work a physically-based model is developed to address slip in polycrystalline metals
and alloys subjected to very high rates of deformation (104–108s− 1). Constitutive relations …

Ultrasonic surface rolling processing (USRP) was applied on quenched and tempered 40Cr.
Microstructure observations of USRP specimen surface indicate that the processing can …

An analytic model of the evolution of dislocation density in fcc polycrystals is described. The
evolution equations approximately account for most known dislocation storage, dynamic …

A reliable and accurate description of the constitutive behavior of metals under the coupled
effect of extremely high strain rate has become more and more important. The conventional …

We present a multiscale strength model in which strength depends on pressure, strain rate,
temperature, and evolving dislocation density. Model construction employs an information …

Thin Fe and Al foils were ramp-compressed over several to tens of ns timescales to study the
time-dependence associated with the onset of plastic flow. Peak stress states of 15–200 …

The response of structures and materials subject to impulsive loads remains a field of
intense research. The dynamic loading and temperature increase affect the material's …

The Rayleigh–Taylor (RT) instability occurs at an interface between two fluids of differing
density during an acceleration. These instabilities can occur in very diverse settings, from …
