“…At larger strains, the variation of the shear modulus cannot be obtained simply from the stress-strain curves due to the nonlinear elastic effect. 34 This prevents us from observing the trend in the change of the scaling exponent in shear modulus at different strains. However, from the results of the stresses, we FIG.…”
