The Model of Dislocation Structure Formation Based on the Theory of Continuous Distribution of Dislocations
Original language description
In the paper focused on the early stages of cyclic plastic deformation, the deformed metal crystal is treated as an elasto-plastic continuum homogeneously filled with mutually interacting loops and glide dislocations. The mathematical model of dislocation patterning is based on the continuum theory of dislocations. It consists of four groups of equations: (i) the crystal plasticity equations, (ii) equations of the continuum theory of dislocations for the plastic strain carried by fluxes of glide dislocations with different initial orientations, (iii) the balance of forces acting on glide dislocation segments leading to an equation of motion for the glide dislocations, and (iv) the balance law for the stored dislocations in the form of the dipolar loops. To demonstrate that the proposed model provides suitable patterns, a simplified version of the model is analysed. A dislocation cell forming crystal is deformed in plane strain conditions by single slip
