In the years passed since the first conference held in 1999 [1] the subject has expanded from isolated pioneering publications to one of the most actively developing trends in materials science and related disciplines such as materials processing technology, solid state physics and chemistry.
Recently the scope of NanoSPD was broadened to include further engineering and medical branches, thus increasing the number of publications in this field to several hundred per year and boasting top-cited papers in leading materials science journals [2].
As a resume of the scientific outcome of the conference, it was stated that bulk nanostructured materials produced by SPD have become an extensively pursued area of research in materials science.
In particular, the International Symposium on Ultrafine-Grained Materials moved its sessions on all aspects of science and technology of bulk ultrafine-grained materials produced by SPD techniques and other techniques.

Guan Institute of Numerical Simulation in Science and Engineering, Department of Computer Science, Tianjin University of Technology and Education, Tianjin 300222, China E-mail: xuanzc@tute.edu.cn Key words: Verification; J-integral; Functionally graded materials; Finite elements Abstract.
Introduction J-integral in functionally graded material (FGM) is an important quantity of interest in material science.
Numerical simulation method has been developed for calculating the J-integral, for example, finite element method is a widely used to compute the J-integral in both homogeneous and nonhomogeneous materials.
By expanding the second integrand, (3) leads to . (4) Using equilibrium () and strain-displacement () conditions and noting that in homogeneous materials, the second integrand of Eq. (4) vanishes, yielding , (5) which is the classical domain form of the J-integral in homogeneous materials.
For nonhomogeous materials, even though the equilibrium and strain-displacement conditions are satisfied, the material gradient term of the second intgrand of (4) dose not vanish.

Thin film and hybrid solar devices, including Dye-Sensitized Solar Cells (DSSCs), are especially promising energy solutions, due to the low cost of materials and equipment required for their fabrication.
Several methods of fabricating nanoparticulate pastes for DSSCs have been studied; among them, the sol – gel method is especially favoured due to the low overall cost of materials, low toxicity of common aqueous synthetic routes, and high quality of the synthetic products obtained [2].

Introduction of Intelligent Materials Intelligent material is the fourth generation materials after the natural materials, polymer materials and artificial materials, it is one of the important development directions of the modern high-tech materials.Concept of intelligent materials was proposed first by Japan scientist in 1989.
Intelligent materials can be divided into optical fiber, shape memory alloys, piezoelectronic materials, magnetostrictive materials and electrostrictive materials etc. according to their different functions.
Relationship between polymer deformation and temperature Conclusion Development and widely application of intelligent materials will result in a major revolution in materials science.
