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 the teaching reform including investigative study and the integration of information technology, is generally accepted that the integration of information technology with curriculum strategy are: optimizing the course structure of space and time, innovation course materials, course materials bag is mainly composed of electronic schoolbag, local curriculum material storage, remote material storage and teaching platform.
And based on the supporting materials, many schools draw lessons from foreign experience, to fixed teaching material in the form of notes, reduce practice principle part, don't write practical steps, mainly is the question for higher College of Engineering students to solve.

Hidden flows and indirect flows Hidden flows are the quantity of the materials which “participate in” the economic activity but not be used, they are not into the process of metabolism but they must be invested into .such as the topsoil and overburden during the process of coal mining, this kind of materials are not into the metabolic process ad consumed by metabolic subject, we called them Hidden flow or Eco-Rucksack.
