Journal ArticleDOI
The crack problem for nonhomogeneous materials under antiplane shear loading — a displacement based formulation
TL;DR: In this article, a displacement-based integral equation formulation for the mode III crack problem in a nonhomogeneous medium with a continuously differentiable shear modulus is presented, which leads naturally to a hypersingular integral equation.
Journal ArticleDOI
Green's function for a two–dimensional exponentially graded elastic medium
TL;DR: In this article, the freespace Green function for a two-dimensional exponentially graded elastic medium is derived and the shear modulus is assumed to be an exponential function of the Cartesian coordinates (x,y), i.e.
Journal ArticleDOI
Strain Gradient Elasticity for Antiplane Shear Cracks: A Hypersingular Integrodifferential Equation Approach
TL;DR: Casal's strain gradient elasticity with two material lengths associated with volumetric and surface energies, respectively is considered, and the question of convergence, as $\ell,{\ell}' \to 0$, is studied in detail both analytically and numerically.
Journal ArticleDOI
Gradient Elasticity Theory for Mode III Fracture in Functionally Graded Materials—Part I: Crack Perpendicular to the Material Gradation
TL;DR: The Fourier transform method is introduced and applied to convert the governing PDE into an ordinary differential equation ODE, and various relevant aspects of the numerical discretization are described in detail.
Journal ArticleDOI
Gradient elasticity theory for a mode III crack in a functionally graded material
TL;DR: In this paper, anisotropic strain gradient elasticity theory is applied to the solution of a mode III crack in a functionally graded material (FGM), which includes both volumetric and surface energy terms, and a particular form of the moduli variation.
