  • From theoretical and experimental aspects, the shear modulus of material at the solid-liquid phase region was discussed when the material has attained its phase transition equilibrium and concluded that the shear modulus did not equal to zero as soon as the material began to melt. Using percolation theory, the connectivity of solid phase in solid-liquid phase region was calculated and the critical melting mass fraction is 0.687 when the shear modulus of material equal to zero. The melting unstable factor of material, presented by us, can represent qualitatively the change of correlative physical parameters in melting process.
