Constitutive model of high solid fraction semi-solid material

The deformed behavior of high solid fraction semi-solid materials is paid attention to. The two-phase constitutive model is built up to describe the de- formed behavior based on the continuum dielectric dynamics and coupled model. The parameters for constitutive model are determined based on isothermal compressive data of semi-solid Al-4Cu-Mg alloy, providing a reference for further investigation of semi-solid material production and numerical simulation as well as practical application.
