The finite element technique is a method which is quickly developed in the calculator science and the basic theories of the rock soil mechanics.
The base parameter of material as follows: concrete density γc=2400Kg/m3,water density γ0=1000kg/m3, sediment buoyant density γc=900Kg/m3.
Conclusions From above calculating result about anti-sliding stability safety factor of the gravidity dam by rigid body limit equilibrium method and FEM, we can get conclusions as follows: the safety factor from rigid body limit equilibrium method is bigger than that from FEM, it signals that rigid body limit equilibrium method is more safe and conservative than FEM. the result from FEM is closer to the gravity dam because it accord with the project fact by considering uneven material.

The Research for Work Roll Thermal Deformation of Cold Rolling Mill with Plastic Materials Peng Yu1,a, Shengli Li1,b, Junsheng Wang2,cand Lei Song2 1 LiaoNing University of Science and Technology, AnShan, 114001, P.R.China 2Anshan iron and Steel Group, AnShan, 114001, P.R.China aoykunpen1@163.com, blishengli66@sohu.com, cphdwjs@126.com Keywords: Cold rolling, Thermal deformation model, Plastic deformation, Friction heat In this article, the factors which have influence on the work roll thermal deformation in cold strip rolling and the heat transferring mechanism are discussed.
It is considered that there are three directions, radial,axis and circumference, for heat transferring for work roll thermal deformation with plastic materials.
Summary (1) The friction heat and plastic deformation with plastic materials work model are built for cold strip rolling considering the change of rolling contact arc along strip width direction.

Electrochromic materials can change their optical properties reversibly with an applied potential due to electrochemical oxidation and reduction.
Polyaniline has emerged as one of the most promising class of active materials for electrochromic devices, due to its high capacitive characteristics [4], easy processing, low cost and environmental stability [5].
CNTs were discovered by Iijima in 1991 [11] and is a very promising materials for application that requires good electronic, mechanical and thermal properties.
