| Résumé : | The properties of persistent slip bands in metals under fatigue and their formation out of the matrix structure are compared with the numerical simulations of a model based on nonlinear reaction-diffusion equations. The persistent slip band structure results from the competition between the mutual interactions of the dislocations and their movement in the slip direction. Numerical simulations of the model equations reproduce the pattern wavelength, the dislocation densities, the wall size and the growth mechanisms experimentally observed. © 1988. |
