A two-dimensional (2D) dislocation continuum theory is being introduced. The present theory adds elastic rotation, dislocation density, and background stress to the classical energy density of elasticity. This theory contains four material moduli. Two characteristic length scales are defined in terms of the four material moduli. Non-singular solutions of the stresses and elastic distortions of an edge dislocation are calculated. It has been pointed out that the elastic strain agrees well with experimental data found recently for an edge dislocation in graphene.
► A 2D dislocation field theory is proposed and used for graphene. ► Non-singular solutions of the stresses and elastic distortions of an edge dislocation are calculated. ► The calculated contour plots of the elastic distortion tensor agree well with recent experimental data.
