Shock induced phase transition of water: Molecular dynamics investigation

Phase Changes in Ni-ti under Laser Shock Loading

Near-equiatomic Ni-Ti, known for its shape memory behavior, can decompose to martensitic phases and/or second phase compounds. This phase competition is investigated in NixTi100-x (49<x<55) in as-quenched (AQ) and shock-loaded states. Dynamic loading was done with direct drive laser pulses of nanosecond duration; shocked samples were recovered for analysis. Unexpectedly, the lowest-Ni alloy (x ...

Proving a phase transition in cellular automata under asynchronous dynamics

Cellular automata are a model of parallel computing. It is well known that simple cellular automata may exhibit complex behaviors such as Turing universality [2,17]. The underlying mechanisms of these rules are now rather well understood (see Kari’s survey [13] or Sarkar’s survey [20]). Less results are known about probabilistic cellular automata. The most famous ones come from Toom [21] and Gá...

The equation of state and nonmetal-metal transition of benzene under shock compression

Abstract We employ quantum molecular dynamic simulations to investigate the behavior of benzene under shock conditions. The principal Hugoniot derived from the equation of state is determined. We compare our firs-principles results with available experimental data and provide predictions of chemical reactions for shocked benzene. The decomposition of benzene is found under the pressure of 11 GP...
