nd_expansionHomoHeatedFoilLJ.avi
Molecular dynamics (MD) simulation of the destruction of a crystal film heated
by a femtosecond laser pulse was carried out. Heating is assumed to be
instantaneous, because there is no time for the material to be displaced
during the pulse. Film destruction is caused by the interaction of unloading waves.
It can be considered as a model of a more complex process of splitting out of a
thin surface layer from a massive target in the case where the layer remains
solid after heating. It was found that the crystal order is broken due to the
stretching strains and to the strong anisotropy of residual stress, resulting
in a bipartition of the layer separating from the target. The lattice stretching
and the formation of anisotropic stresses are due to the expansion of a heated
lattice.

C_dislocationsPlsticWaveLJhomo.avi
Molecular dynamics (MD) simulation of expansion of quickly heated Lennard Jones
(LJ) crystalline thin ?lmis performed. The heating time is assumed to be much
shorter than the characteristic expansion time. Such situation occurs when a
femtosecond laser pulse is absorbed by a crystal. We established that plastic
rarefaction wave is formed and propagates from the vacuum boundary into solid.
