The mechanism of homo-heterogeneous melting of aluminum with subsequent fragmentation of the melt under the influence of an ultrashort laser pulse is implemented within the framework of a nonequilibrium continuum model with dynamically adapting computational grids. The interaction of slow heterogeneous and fast homogeneous melting is investigated. Melt parameters and features of mechanical fragmentation of the liquid phase of the metal due to negative pressure developing in the hydrodynamic unloading wave are determined.
