Experiment of the SCT Joint under Complicated Loading Bing Liao a, Yongfeng Luo b, and Xiaonong Guo c Tongji University, Shanghai, 200092, China aLake997@163.com, byfluo93@tongji.edu.cn, cguo-xiao-nong@tongji.edu.cn Key words: SCT Joint, Test of Full Size Model, Complicated Loading.
Following assumptions are adopted in the finite element analysis of the test joint model. ① The thickness of weld root and the residual stress of welding are ignored in the load-bearing calculation of the test joint. ② The steel is isotropic material, and obeys the Von-Mises yielding criterion. ③ The idealized elasto-plastic model is adopted as the constitutive relation for steel, and the mechanical property of steel is obtained through the material test [6].
The reasons of the deviation are clarified as follows [9]. ① The strengthening phase of the steel material is ignored in the finite element calculation. ② The calculation model cannot simulate the test condition perfectly.

Introduction Polyurethane (PU) materials are of commercial interest in many applications because of their excellent properties such as abrasion resistance, chemical resistance, toughness combined with good lowtemperature flexibility [1].
Therefore, natural fibres can serve as reinforcement by improving the strength and stiffness and also by reducing the weight of the resulting biocomposite materials [5].
Experimental Materials: Castor oil (Mn is 930, hydroxyl group/molecule is 2.24) was procured from SD fine chemicals.
Silk fibers found to reinforce the PU matrix by allowing a greater stress transfer at the fiber-matrix interface, therefore increasing the stiffness of the overall material.

Experimental The Ni-40.2Cr alloy used in this investigation was prepared using Ar-arc melting from commercially pure Ni and Cr metals as starting materials (99.99% purity).
In addition to these alloys the barrier coating of Re-based alloy was found to improve oxidation resistant of high temperature materials such as Co-based alloys and Stainless steels.

Key requirements for success in engineering spintronics devices using spin injection via a FM electrode in a diode (or junction) include the following: (i) efficient injection of spin polarized (SP) charge carriers through one device terminal (i.e.
Before we move on to listing the progress made thus far in the field of Molecular Spintronics, and the current challenges facing it, we shall first discuss some key concepts related to the use of organic materials in spintronics.
Many materials respond to an applied magnetic field with a change in conductance.
As spin electronics learns from organic electronics and organic chemistry, we can foresee the emergence of a phase of ‘spinterface engineering’ to provide guidance on how best to get the spins moving into these structures.

And the research was about the theoretical basis for Well bore control theory of top drive drilling. 1 Vibration theory analysis of FMB drill string system based on FSI 1.1 Dynamics model of FMB drill string system FEM in drilling engineering was used in the late 1970s [11, 13].
Put them into equation (3), and the lord vibration mode vectors were obtained, that were n natural mode of vibration of flexible multi-body drill string system. 2 Pre process of FE analysis of FMB drill string system based on FSI 2.1 Fundamental assumption and model parameters of the system Basic hypothesis: The drill string is linear elastic straight pole; The original axis of drill string is coincident with borehole axis before the oil drilling; the geometric dimensions and material properties of drill string are piece wise constants; The small deformation of drill string elements are caused during the process, which can be adaptable to arrange; The drill fluid is supposed as Newton fluid; The hydrodynamic pressure of drill fluid is zero; The temperature affection on the drill string vibration is negligible.
