u- and v-fringe shapes and corresponding deformation stage.

Case	$G (\nabla \times ω)$	$G J$	Deformation Stage Criteria
(1)	0	0	uniform elastic deformation (principal axes)
(2)	0	0	rigid-body rotation
(3)	0	0	uniform elastic deformation (non-principal axes)
(4)	$- {Gb}_{2} (x - x_{0}) \hat{i}$	$- 2 (λ + 2 G) b_{2} y \hat{j}$	plastic deformation
(5)	$- G (b_{2} (x - x_{0}) \hat{i} + c_{2} (y - y_{0}) \hat{j})$	$- 2 (λ + 2 G) (c_{2} x \hat{i} + b_{2} y \hat{j})$	plastic deformation
(6)	$- G (b_{2} (x - x_{0}) \hat{i} + c_{2} (y - y_{0}) \hat{j})$	$- 2 (λ + 2 G) (c_{2} x \hat{i} + b_{2} y \hat{j})$	plastic deformation
