Structural Transformations in Materials under Dynamic Loading

Abstract—The loading of a metal rod whose material contains impurities and is described on the basis of a two-component continuum model is considered. The proposed two-component model allows us to take into account the role of dynamics in the transition of a material from one state to another, using source terms in mass balance equations. The obtained solution demonstrates the significant influence of evolutionary processes on the restructuring of the structure defined by the equation of state
