Effect of Crack Statically Growing on Stress and Strain at Crack Tip for Power Hardening Materials He Xue 1, a, Min Qiao 1,b , ZhenWen Wang 1,c , XiaoYan Gong 1,d 1 School of Mechanical Engineering, Xi’an University of Science and Technology, 710054, China axue_he@hotmail.com, bqiaom_1989@163.com, c2007.wzw@163.com , dgongxymail@163.com Keywords: crack statically growing; residual plastic strain; power hardening materials; elastic-plastic finite element Abstract.
Numerous austenitic stainless steels and nickel-based alloys are power hardening materials, which is widely used in key structural materials of nuclear power plants.
Therefore, the re-distribution of stress and strain at the growing crack tip in power hardening materials will be discussed by using ABAQUS software in this paper, which provides a foundation for quantitative predicting environmentally assisted cracking growth rate in key structural materials of nuclear power plants.
The numerical simulating test process satisfied American Society for Testing and Materials (ASTM) E399 standards.

The problem following is that process brings too much unrecycle talc paper plate leftover materials when the talc paper plate is cut out and molding.
Those leftover materials always be abandoned as crab.
Different concentrations of immersion materials indicate the same variation rule.
Influence of immersion concentration Figure2 indicates that decomposition rate increases as concentration of immersion materials increases, but the variation amplitude is less.

On Position of Information Science In Complexity Research Information idea is that the people carry information as a kind of the basic existence for difference from material (quality and energy ), as well as the generality understanding, stipulation and knowledge that made for its essence, existent way, meaning and value.
This is not accidental, because uncertainty information produce is the inevitable result of material sport.
