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.

It is thus of some interest to understand the dynamic behavior of masonry materials under dynamic loading.
Based on the constitutive relations of the brick and the mortar materials, the equivalent stress-strain relations of the RVE are homogenized by applying various compatible displacement conditions on the RVE surfaces.
They are defined as and (3) in which and are damage parameters that control postfailure stress-strain relations of materials in tension and compression.

Nanometer materials and their application technology as an important part of nano science and technology, is considered to has a decisive role to the development of contemporary science and technology.
In order to promote the development of nano science and technology, in July 1990 in the United States in Baltimore held the first international conference of nanotechnology, and announced that "nanotechnology" the international journal.
Nanometer materials.
Countries engaged in materials science experts and scholars are desire to develop new nano materials (especially the nano composite material), seeking for new technology of the preparation of new nano materials, to further explore the particle size of nanometer material, the amount of phase interface, the interface phase relationship between atomic structure and nanometer material performance, and the diffusion process of nanometer materials, the formation mechanism of nanocrystalline ceramics (especially the reticular formation) for further research.
