Color Features of Modern Architectural School Due to constant innovation on new materials and new technologies, various architectural schools constantly emerge.
After World War II, people began to use plenty of colored glass, transparent plastics, light metals and other materials extensively in new buildings.
Its aesthetics rooted from the "real" expression of pre-war "modern architecture" through materials and structures.
A Critical History of Modern Architecture wrote “science is constantly enriched himself and life, and constantly uses newly found useful materials and specific forces of nature, new methods and techniques, as well as new tools and machines”, “the hardest porphyry and granite can be cut like butter and polished like wax.
Flexible Malay rubber after high temperature sulfur treatment can be made into high simulation products of real wood, gold or stone carving, far beyond the natural texture of the imitated materials".From this, we can see that with the science and technology rapid development, people have more choices on architectural materials.

Materials properties.
The substrate material was considered to bilinear hardening materials comprising of elastic modulus and tangent modulus.
Materials properties used in finite element simulation were summarized in the Table 1.

Introduction Metal materials including stainless steel, titanium alloy and cobalt-chromium-based alloy can keep stable structure for a long period in human body due to their good corrosion resistance properties; they have been widely used for implantation into human body as biomedical materials in clinic, such as artificial arthrosis, artificial tooth, oral cavity implanting materials and artificial heart valve.
But disadvantages also exist for these permanently implanted metal materials.

Fig. 1 FDY-1.2 portable wind erosion wind tunnel Filling materials of subgrade model chooses the Aeolian sandy soil that was taken from the heartland of Hobq desert in Ordos altiplano and under the surface soil depth for 3m-5m.
Subgrade slope is eroded and filling materials of subgrade will be changed in influence of wind-sand flow intensity, blowing time, soil property etc.
l The blowing time are selected 20min and 40min, and analyzed pore changes of filler materials under different blowing time.
