The level of density also relates to the space between molecular materials.
There are two sizes of materials, 1 and 3 cm.
At the F/S ratio of 0.025, 1 cm gave 1.40% yield, and 3 cm size materials produced 1.25% yield.
Power of 2100 W gave the highest yield for both 1 and 3 cm sized materials.

Introduction Steel and concrete continuous composite girders are widely used in multistory buildings and long span bridges due to the benefits of combining the two construction materials [1].
The mechanical behavior of the composite structure was not only determined by the properties of different materials, but also influenced by the connection structure between different materials.

In the paper, diasporic bauxite and RMG were respectively used as starting materials to prepare PAFC.
Experiment Materials and Apparatuses in Experiment Hydrochloric acid, diasporic bauxite and RMG are used as main materials in the experiment.
Leaching ratios of alumina and iron oxide increase notably if RMG is used as raw materials.
Diasporic bauxite is not suitable for raw materials for PAFC, while RMG is chosen as raw materials.

Study on the Formulas of the Dog-bone Shape of Edger Rolling in Hot Strip Mill Aili WANG a, Quan YANG b, Huaqiang LIU c, Xiaozhong DU d ,and Xiaochen WANG e National Engineering Research Center for Advanced Rolling Technology, University of Science and Technology Beijing, Beijing 100083 a wal9709@163.com, byangquan@nercar.ustb.edu.cn, clhuanqian@163.com, d xiaozhong_du@163.com, e wangxiaochen198266@yahoo.com.cn Keywords: hot strip mill;the main parameters of the dog-bone shape;3D elastic-plastic FEM model;edger roll Abstract. 3D elastic-plastic FEM model was established with ANSYS/LS-DYNA for edger rolling in hot strip mill.
Finite Element Model Simulation principle was based on dynamic explicit elastic-plastic finite element method, the slab was set a bilinear kinematic hardening elastic-plastic material model and the edger roll was set rigid-plastic material.
With the increasing of the width reduction, the contact length between the slab deformation zone and edger roll becomes longer, so the volume of the plastic deformation material flow increases, and deformation zone form factor(le/hm, the contact length between the slab and the edger roll/the average thickness of the slab) also becomes larger, which makes the longitudinal plastic resistance increasing.
