Fig.4 Subregional analysis diagram Set the material parameters.
General material parameters typically include the relationship between viscosity, shear rate and temperature, fluid viscosity, integral-differential visco-elastic model, thermal expansion coefficient, unit mass heat capacity, density, thermal conductivity, gravity, viscous heating and so on.
It can be seen from the Figure 5, die extrusion that is section from inlet to z=100mm, the rubber material is fully developed, The end that is z=240mm to end section where speed of development is a constant value, Between the extrusion and the end that is z=100mm section to z=240mm section as a transitional stage, neither fully developed nor constant.

Synthesis and Characterization of a Novel Alkaline Earth Metal Complex Huifang Yang1, a, Shuxia REN 1, b, Huang Li1,c and Junjun Shen1,d 1School of Material Science and Engineering, Shijiazhuang TieDao University, Shijiazhuang, Hebei, 050043, China a yhf989@sina.com, bren-shu-xia@163.com, chuangli@163.com, d junjun@sina.com Keywords: Azobisisobutyronitrile, Alkaline earth metal, Complex, Structure, Thermal behavior Abstract.
Introduction With the development of modern society and progress of science and technology, a lot of alkaline earth metal complexes have been shown the great potential in the field of business and have attracted much more attention in the world because the majority alkaline earth metal ions are poisonless, cheap and excellent solubility which lead to their application in the fields of medicine, catalysis, dyes, pigments, and materials obviously superior to the transition metal and rare earth metal ions.

As a new fiber material, igneous rock fiber reinforced polymer(IFRP) is a cost-effective, good comprehensive performance.
No-yield-point steel constitutive model was used to describe the material property of rebar.
The mainly reasons are: (1) when wrapping IFRP to the columns, there was some disturbance to the strain gauges; (2) the constraint of simulation models and the method of loading couldn’t be the same to the experiment; (3) concrete of simulation models is a homogeneous and isotropic material, but concrete in real life is discrete and its homogeneity could be impacted by construction method.
(3) The strengthening effect of secondary-load RC square columns is closely related to the ratio of first load to the compression capacity Acknowledgements The supports of the paper by the National Natural Science Foundation of China under Grant No. 51279181 and the Science and Technology Plan Project of the Ministry of Water Resources of P.
