Fig. 4From: Strain gradient elasticity with geometric nonlinearities and its computational evaluationStiffening due to the size effect. The blue dots (connected with the continuous line) denote simulations with β=−1 mN and the red diamonds (connected with the dashed line) are computed by setting β=0 mN. By increasing the length of beam, ℓ, the strain gradient corresponds with the classical theoryBack to article page
