Suggestions for the achievement of an "economic and ecological" Circular Economy Enhance the economic foundation of theory and method in CE research We have raised a new work called material economic metabolism analysis, which means how to evaluate the total material demand scale of the economic system and how to evaluate the process of the material flow(throughout) according to the social and economic production, and what are the main influence factors to enhance the using efficiency of raw materials and energy.

For other materials, there is plotted a line with slope coefficient mD (15 for normal stress and 25 for shear stress) up to 108 cycles.
It must be noted that the results are the results of preliminary investigation and further investigations should be performed for other engineering materials.
