ℹ️ About

An edge dislocation is an extra half-plane of atoms in the crystal lattice, marked by ⊥. When applied stress exceeds yield stress τ_c, the dislocation glides through the lattice — a Burgers vector b displacement per slip event. This is the atomic mechanism of plastic deformation: dislocations move rather than all bonds breaking at once, requiring ~1000× less stress. Temperature enables thermally activated glide below τ_c.
