FEM Simulation and Experimental Results Effects of Material Thickness.
However, the increase of the material thickness and the decrease of hole-flange forming ratio, resulted the material was difficult to move downward.
The material thickness affected the bending feature and material stretching and these effects could be theoretically clarified on the basis of stress distribution analysis.
As the material thickness increased, the effects of bending feature and the material stretching increased resulted in the crack formation was easily generated.

In recent years, ultraprecision grinding was researched as a new method used for hard and brittle materials, and the key here is how to realize material removing mostly by ultra-micro cutting and ductile shearing action.
Consequently, for ultraprecision grinding of hard and brittle materials, it’s difficult to identify material removal modes and define surface generating mechanism.
Plastic shearing mechanism of hard and brittle materials in ultraprecision grinding In 1987, a notable hypothesis was putted forward by American scholar T.G.

How to Operate Energy-saving Technologies of the Classroom in Hot Summer and Cold Winter Zone Wei Shi ，Jiang Du C8, Huazhong university of science and technology, Wuhan C11,Huazhong university of science and technology, Wuhan 404，South 4，Huazhong university of science and technology, Wuhan 277306232@qq.com, 309907107@qq.com Keywords: Energy-saving , Ecological System,Reconstruction Abstract: Through the reconstruction project of teaching building in Huazhong University of Science and Technology, several effective and detail strategies of Energy-saving technologies has been researched for sustainable building in hot summer and cold winter area.
In this thesis, Huazhong University of Science and Technology, Wuhan, Hubei College of Architecture and Planning Teaching Building as an example analysis of building Energy-saving technology in existing buildings applications.
Meanwhile, in order to promote green, healthy, eco-learning environment, combined with climatic characteristics in Wuhan it can be proposed a reconstruction strategy： Fig 2 Mainly using the ecology principle, considers the ecosystem to the construction system's energy as well as the material input and the output ,the ecosystem to the construction system's function, the energy and the material in the construction system interior movement to the construction system's function, as well as energy and material how in construction system interior movement and so on several aspects.
