Chuan Gu studied the influence of cyclic loading history on small strain shear modulus of saturated soils by triaxial test; test results show that both cyclic strain history and cyclic stress history will induce reduction of Gmax compared to the corresponding Gmax values with noncyclic loading effects at the same effective stress [9].

Recently Ecsedi showed that, for functionally graded cross sections under torsion, with shear modulus defined by a positive function of the Prandtl stress function of a corresponding homogeneous cross-section, the warping is invariant and the stress function is expressed in terms of the one associated with the reference homogeneous cross section [55, 56].
