Due to the geometrical and material symmetry only one quarter of the global structure is modelled.
The main differences occur in the cup’s wall as a consequence of the changes in the material flow.
However, it is know that Hill’48 yield criterion does not represent accurately this type of materials (r<1).
During this experimental study, an effect of material’s anisotropy was also detected.

Tribological and oxidation properties study of a kind of sodium sulfonate-modified nano carbonate sodium He Zhongyi1,2 a,Xiong Liping1b,Xu Huan1,Li Tao2,Qiu Jianwei2,Fu Xisheng2 1)School of Basic Science, East China Jiaotong University, Nanchang, PR China 2)PetroChina Lanzhou Lubricating Oil R & D Institute, Lanzhou, PR China aemail:zhongyihe@yahoo.com.cn; bemail:zhyhe@ecjtu.jx.cn Key words: alkali metal sulfonate; nano carbonate sodium; tribological property; antioxidant Abstract: The tribological properties of a high base value sodium sulfonate-modified nano carbonate sodium as lubricating oil additive were introduced in this paper, and its antioxidant collaboration property with ashless antioxidant was evaluation by using pressure differential scanning calorimetry(PDSC).
To study tribological property of sodium sulfonate which containing nano carbonate sodium applied as extreme pressure additive, and it’s antioxidant synergistic effect with antioxidant T531, alkyl benzene sulfonic acid was used as raw material to obtain high base value sodium sulfonate, and it’s tribological property was evaluated by using a four-ball machine in hydrogenation oil, its antioxidant property with T531(N-phenyl-α-naphthylamine) was also discussed in this paper.

Protein is the material basis of life, no life without protein.
Human protein content and intake and metabolism related people frequently engage in sports training, can consume a large protein, while protein intake but also far more than normal, so to supplement the protein consumed, but also save as part of the protein material foundation movement.
