The material nonlinearity of structure is considered with reinforcement concrete fiber model, and distributed hinge type is adopted to simulate for plastic hinge.
Main idea of fiber model is to discredited analysis cross section into certain fibers, assuming every fiber to be in uniaxial loading, while the cross section deformation using the plane section assumption, and nonlinear relationship of force and displacement of whole cross section can be calculated by relationship of uniaxial strain and stress of fiber materials.

Corrosion behavior of Incoloy 800 in molten nitrate salt Zhang Yujun 1, a, Xiao Leilei 1, Liu Junhua 1, Liu Meiling 1, Fu Minhui 1 1 Material Science and Engineering School, Xi’an University of Science and Technology, Xi’an 710043, China a zhangyuxiou_dl@163.com Keywords: Incoloy 800; Corrosion; Oxidation; Molten salts.
For the safety of the molten salts STP plant, the corrosion behavior of candidate receiver tube materials used in such an aggressive environment needs to be understood well [5-6].
High nickel alloys have been considered as one kind of candidate materials due to their combined good corrosion resistance and mechanical properties in high temperature molten salts.

The Si implanted materials have a markedly increased erosion resistance than unimplanted siloxane coatings in AO environment.
Polymer materials used in spacecraft are usually damaged both chemically and physically by these environmental factors.
Major environmental factors related to the degradation of polymer materials’ properties are AO, UV, and radiation.
The surface of implanted polymer based materials combines the advantages of inorganic materials and organic polymers.

A BOUBAKER POLYNOMIALS EXPANSION SCHEME FOR SOLVING THE FLOW OF NONLINEAR POWER-LAW FLUID IN SEMI-SOLID STATE Wang Kai-kun 1,a), Fu Jin-long 1,b), Si Xin-hui 2,c) 1 School of Materials and Engineering, University of Science and Technology Beijing, China 2 School of Mathematics and Physics, University of Science and Technology Beijing, China a) kkwang@mater.ustb.edu.cn ; b) jinlongsjz@126.com; c) xiaoniustu@163.com Corresponding author: WANG Kai-kun; +86-010-62332598-6117; E-mail: kkwang@mater.ustb.edu.cn Key Words: Boubaker Polynomials Expansion Scheme; Power-law fluid; Unsteady stretching surface; Semi-solid state.
The flow of an uncompressible power-law fluid on an unsteady stretching surface has been widely applied in the process of material engineering, for instance, the extrusion of aluminum and magnesium alloys in semi-solid state.
In the forming process, the material in the center is formed in flow state while the ambient material is stagnant.

These findings lay a solid foundation for the further development of bridge safety assessment and prediction when non-linear chaotic theory is utilized to analyze the bridge health monitoring information. 1.Introduction Bridge structure as a complicated mechanism model is subject to influences of multiple factors as structure form, materials and external circumstances, and during actual operation necessarily shows highly non-linear characteristics[1].
In the late years of the last century, the nonlinearity sciences including chaos, fractal and so many leading sciences which had offered the possibility to research time sequence with non-linear instruments had had great developments.
