The theme of decoration engineering has its own characteristics different from other engineering in several factors in the idea, positioning, functions and social influence of the project, and the said theme shall penetrate in the entire construction process.
This process may be divided into steps of ascertaining the target, collecting materials, conducting creation and validating the creation.
In the age of fast economic development, the issues of social benefits shall be always noted by each engineering technical personnel.
The designer shall be good at using advanced materials and means to put sound foundation for realizing the design idea.
Now matter how environmental friendly are these materials, they are after all chemicals and their contamination completely exists.

So the material of water-based key components is required to be modified to improve its wear properties.
Table 1.1 shows properties of common ceramic materials.
The key point to reduce wear even no wear is to make sure the high hardness and the excellent compression performance of the ceramic materials.

Numerical Model of Road Tunnel with Void between the Liner and Surrounding Rock and Its Application Jia-yan Zheng1,a, Hai-jing Liu2,b 1Key Laboratory of Bridge-Structure Engineering of Ministry of Communications, Chongqing, 400074, China 2 Chongqing Communication Research and Design Institute, Chongqing, 400067, China ajyzheng@126.com, bliuhaijing@cmhk.com Key words: tunnel, void between the liner and the rock, computational model, safety assessment Abstract: Void between road tunnel liner and surrounding rock is one of the most frequent defects in tunnel engineering.
In geotechnical and tunnel engineering, Goodman element is used most to simulate the interaction and study the mechanism of the liner and the rock.
The surrounding rock of the tunnel is considered to be ideal elastic-plastic material following non-associated Drucker-Prager yield law while the liner is considered to be isotropic elastic material.

The principle of extracting the engineering semantic is shown in Fig.2: (1)First, the attributes of parts are read, and the handles of geometry features annotated with engineering semantics are found; (2)Then, the geometry features annotated with engineering semantic are found according to the handle; (3)The engineering semantic which saved in the features is loaded and the key geometry descriptions of features are extracted and can be identified by "featureid".
Fig. 2 The method for extracting the engineering semantic markup Feature extraction.
The model then is not only the geometry model but the physical model with the engineering semantic.
Fig. 4 The method of finding features which are marked engineering semantic XML mapping algorithm.
XML files have the tree structure, when using the engineering semantic annotated XML files to map the FEA template files based on XML, the FEA template act as query tree, engineering semantic files act as data resource tree.

A Theoretical Model of Strain Measurement System of Membrane Materials in Biaxial Tensile Tests Mesrop Andriasyan1,a* 1Textiles HUB, Politecnico di Milano, ABC department, 9, Bonardi street, 20133, MI, Milan, Italy amesrop.andriasyan@polimi.it Keywords: Tension membrane materials, structural test, biaxial rig, strain Abstract.
The proposed model is based on the reverse engineering of Delta 3D printing system.
Tensile tests may be applied to a wide range of materials both rigid and flexible.
The key difference is that the workflow is reversed.
The Textiles Hub provided access to its facilities, equipment and information about testing procedures References [1] Testing method for elastic constants of membrane materials, Mebrane Structures Association of Japan, 1995

Examples are given of test measurements of the characteristics of the structure and properties of elements used in key materials of modern technologies, as well as some compounds based on them.
New materials and methods of controlling the key parameters of phase transitions in substances, especially of the cooperative (collective) type, are being developed.
Among them emerging new important phases, defects and processes from which engineering materials are described, as well as taking into account the synergy of their influence.
In this paper, we consider 3D-models for technologists based on the methods of multi-factorial analysis, for the recognition and subsequent classification of the key characteristics of materials.
In this case, these are the mass and amount of substance as two complementary forms of the matter, or in engineering as a unit for controlling the operation of a device or a system of connected devices.
