In this study, a well‐defined finite‐deformation gradient crystal plasticity is employed to study size‐dependence strengthening behavior of a single crystal under simple shear loading. The constitutive model is implemented in the FEM software ABAQUS via a user‐defined element subroutine (UEL). Effect of gradient strengthening, latent hardening and scale‐variation in mechanically plastic response of a single crystal subjected to isothermal quasi‐static loading is studied and discussed.
