FEM analysis of Bi-prestressed Concrete Beam Gao Feng1, a, Tong Liu2,b 1School of civil Engineering and Architecture , Southwest university of science and technology, Mian yang, Sichuan, 621000, China, 2 Southwest university of science and technology, Mianyang, Sichuan, 621000, China, a491786104@qq.com, btliu@swust.edu.cn Key words: pre-pressed; pre-arch;bi-prestressed ; FEM Abstract: Based on ANSYS software, the solid modeling method was performed to build the half model of bi-prestressed concrete beam.
Material constitutive relation and failure criterion of timing , pre-press steel, ordinary steel, steel strand of constitutive model are used in Fig 1,Fig 2, Fig 3 shown in dual linear servo intensive model(we called BKIN), the model adopts the Mises yield criterion and follow-up to strengthen standards with two straight lines describe materials ideal elastic-plastic stress-strain relationship [6].In ANSYS, using multiple linear models to strengthen (we called MISO) was simulated, which is showed in Fig 4 .

Refractive index temperature coefficient of infrared optical materials is much larger than the visible material from the data in Table 1.
When the refractive index of optical materials is changing, light optical path will also change [8].
The materials which we chose are zinc selenide, zinc sulfide and germanium.

Introduction Demand for natural fiber composites which are made from renewable raw materials increase as an attempt to reduce the use of fossil materials that have problems with the environment [1,2].
This is because composite materials with natural fibers have an environmentally superior quality compared to glass or any synthetic fiber [3,4].
