| Özet |
| The displacement and stress fields were derived from Fourier analysis for hexagonal network of dislocation, which are periodic in two-dimensions. Analytical solutions were obtained within the framework of isotropic elasticity theory for a situation in which one of the media tends to infinity and the other is of thickness of h. By employing appropriate boundary conditions, the coefficients of displacement and stress fields have been found. These coefficients clearly show that the displacement and stress fields depend on h (thickness),(shear modulus),(Poisson's ratio), the geometry of the network of dislocations and Burgers vectors. authors have investigated the relationship between the geometries of the networks and the Burgers vectors10, 9, 8.In this study, the displacement and stress fields are determined by a classical Fourier series analysis. The two phases are supposed to obey classical Hooke’s law and assumed to be elastically isotropic. The stress fields are derived from the displacement fields via Hooke’s law. |
