Rubberized portland cement concrete is concrete as base material, uniformly mixing various non-continuous rubber powder and rubber particles and the formation of cement based composite materials.
Frame system of the main building structure can use the wall of the new energy efficient building materials in this region which was warm in winter and hot in summer.
Research and application of concrete pavement materials that has modified have achieved good results at home and abroad.
At present, rubberized portland cement concrete is applied as materials of the surface layer of the toughness, expansion joints and elastic material that repairs expansion joints crack in the project of Shanghai Outer Ring Road, Inner Ring Viaduct.

However, there are many problems in the traditional processing method such as: low efficiency, wasting materials and instable quality, etc[1].
Cold extrusion forming process not only can improve productivity, but also improve the utilization of materials and mechanical properties of parts.
Metal materials flow upward with the upper protruding die downward because the backward extrusion resistance is less than forward extrusion resistance.
Materials mainly flow downward.

Design and Analysis of a Novel Permanent Magnet Arc Guideway Motor Gong Zhang1,a, Kun Wang 1,2,b, Yinpin Wang1,c, Xuefeng Zhou1,d, Xianshuai Chen*1,e, 1Precision Engineering Research Center, Guangzhou Institute of Advanced Technology, Chinese Academy of Sciences, China 2School of Electromechanical Engineering, Guangdong University of Technology, China; agong.zhang@giat.ac.cn, bkun.wang@giat.ac.cn, cyp.wang@giat.ac.cn, dxf.zhou@giat.ac.cn exs.chen@giat.ac.cn Keywords: permanent magnet; arc guideway motor; magnetization; electromagnetic force Abstract: Based on the application drawback of the conventional motor reciprocating within certain angle, a novel permanent magnet arc guideway motor (PMAGM) is put forward which directly converts electrical current into limited angular moment, producing torque through a limited rotation angle of normally much less than ±180º.
Magnetization techniques In this paper, the PM material of PMAGM is adopted Nd2Fe14B material, giving a theoretical maximum energy product (BH)max up to 515 kJ/m3, as compared with ~64MGOe [8].

The same flexural members, different structure form, it’s mechanical properties will be various greatly, so the author will use the Finite Element Method, based on reasonable stress-strain constitutive model of the material and the failure criterion of the composing materials, simulate and analise the mechanical properties of Square Steel Tubular High-strength concrete inner set CFRP round pipe flexural members.
This paper specifies it as Elastic brittle material to express it’s mechanical behavior.
