2Transport properties of warm and hot dense iron from orbital free and corrected Yukawa potential molecular dynamics显示文摘The equation of states,diffusions,and viscosities of strongly coupled Fe at 80 and 240 eV with densities from 1.6 to 40 g/cm^(3) are studied by orbital-free molecular dynamics,classical molecular dynamics with a corrected Yukawa potential and compared with the results from average atom model.A new local pseudopotential is generated for orbital free calculations.For low densities,the Yukawa model captures the correct ionic interaction behavior around the first peak of the radial distribution function(RDF),thus it gives correct RDFs and transport coefficients.For higher densities,the scaled transformation of the Yukawa potential or adding a short range repulsion part to the Yukawa potential can give correct RDFs and transport coefficients.The corrected potentials are further validated by the force matching method.H.Y.Sun Dongdong Kang Yong Hou J.Y.Dai 2017Matter and Radiation at Extremes2017,2,6:1
3EXTRUSION DIE CAE OF THE STEEL REINFORCED PLASTIC PIPE显示文摘The steel reinforced plastic pipe is a new kind of pressure pipe. It is made up with steel wires and plastic. Because reinforced skeleton of the steel wire increase the complexity of plastic flow during the extrusion phase, the traditional design criteria of extrusion die is not suitable. The study on extrusion die of the kind of pipe is very important step in produce development. Using finite element (FE) method in this paper, the flow rule of molten plastic inside the die has been predicted and a group of optimal structural parameters was obtained. These results are helpful for reducing the design cycle and improve the quality of the final product.W.Q.Ma H.Y.Sun D.C.Kang K.D.Zhao 2004Acta Metallurgica Sinica(English Letters)2004,17,3:0
