“…The values of Young's modulus of matrices vary from 5GPa to 500GPa with the poisson ratio 0.25 to cover soft and hard matrices. To simulate this infinite matrix and avoid the large volume meshing in the matrix, the so called body force method was applied here [4,5]. Based on body force method, the stresses and displacements in matrix can be expressed by a simple superposition of unknown distributed body forces acting along the interface between CNT and the matrix as following, ,…”

In this paper, the strength of the singular stress field near the ends of the CNTs in composites was analyzed to clarify the effects of the CNT length on stress filed in the CNT reinforced composites when studying the fracture toughness. The singular stress field was separated into two types of singularities, symmetric and skew-symmetric, near the ends of CNTs according to the deformation and loading types. The stress intensity factors of the singular stress field were calculated for these two types of singularities. The effects of the CNT length in CNT reinforced composites on these stress intensity factors were investigated.

“…3 when point P'' coincides with point Q. Details can be found in the papers [4,5]. σ** ij (P,Q η ) and U** ij (P,Q η ) are the stress and dispalcement components at point P, in an infinite media with the same elastic constants as the CNT, due to a unit body force acting at point Q on interface Γ and in η direction.…”

“…Connected to this paper, Chen et al (1997Chen et al ( , 1998 and Li et al (2000) have considered anti-plane shear problems for a crack between two dissimilar homogeneous piezoelectric materials. In this paper, we have solved the equations of equilibrium by the method discussed by Dhaliwal & Singh (1978).…”

In the present paper, the dynamic behaviour of a Griffith crack situated at the interface of two bonded dissimilar functionally graded piezoelectric materials (FGPMs) is considered. It is assumed that the elastic stiffness, piezoelectric constant, dielectric permittivity and mass density of the FGPMs vary continuously as an exponential function of the x and y coordinates, and that the FGPMs are under anti-plane mechanical loading and in-plane electrical loading. By using an integral transform technique the problem is reduced to four pairs of dual integral equations, which are transformed into four simultaneous Fredholm integral equations with four unknown functions. By solving the four simultaneous Fredholm integral equations numerically the effects of the material properties on the stress and electric displacement intensity factors are calculated and displayed graphically.
