Numerical Simulation of Series Experiments of Concrete Fracture Deng Aimin 1,a, Wang Xiangdong 1,b, Xu Daoyuan 1,c 1 Department of Engineering Mechanics, Hohai University, Nanjing 210098, China ad-a-m@sohu.com,bwwang90@sohu.com, cwwwkkty2002@yahoo.com.cn Key words: numerical simulation; concrete fracture; ANSYS; experiment; non-linear Abstract: With progress of the computer technology and numerical simulation method, the numerical simulation of the fracture process of concrete materials has become possible.
Taking into account the nonlinear characters of concrete materials, the SOLID65 element is introduced in ANSYS.
At this time, the material of the element is non-linear, and the iterative solver is required [5].

Laser allows short-time surface engraving of the patterns of desired variety, size, and intensity on a wide range of textile surfaces with precision and without much damaging the texture of the materials.
As a result, more fiber materials together with the blue indigo could be removed from the fabric surface giving finally a paler shade.

This paper introduced the optical principles and the preparation of raw materials used to composite transparent soil.
The main representative of foreign research results are: A1lersma etc[9] use the broken glass and fluid which has a corresponding refractive index as transparent medium to study shear stress distribution under conditions of materials; Konagai etc[10] studied the seismic loads using the above material under the stress of saturated dike.

This process is applicable as a surface treatment for improving chemical resistivity of the soft materials.
In this paper, we demonstrate the SiO2 ALD on the soft materials of acrylic resin and polystyrene.
We also discuss the reaction mechanism of SiO2 deposition on the soft plastic materials.
