    • note
    • In this work we do not consider fracture or brittle behavior. Following Argon et al. [16, 18], we use the term "shear band" widely to represent quasilinear (in 2D) [or quasiplanar (in 3D)] objects where shear strains are localized. The narrowest ones are slips composed of dislocation pairs.

    • Typical applied stress is tensile, compressive, or shear. In experiments uniaxial deformation is more usual than shear deformation.

    • note
    • If ρ is included as a dynamic variable, ρ obeys the continuity equation ∂p/∂t = -∇ (ρv) and the right hand side of Eq. (2.17) should be replaced by ρ[∂/∂t + v · ∇]v. Then the self-consistency relation (2.20) is kept to be valid. For large strains of order 1 this generalization is needed.

    • In 2D, the glide direction is along the Burgers vector b, and the climb direction is perpendicular to b [1,2].

    • note
    • The Peierls potential energy depends on the ratio of the atomic spacing across the glide plane and the magnitude of the Burgers vector [1, 2, 44, 45]. As a result, the critical stress causing dislocation motion (Peierls stress) can strongly depend on the orientation of the glide plane with respect to the crystal axes.
