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].
