WebThe dynamic shear modulus ( Gd) and damping ratio ( λ) of the expansive soil samples are improved by reinforcement. Reinforced soil can inhibit the axial compression of the sample and restrain the frost heave deformation of the sample during the freezing process. http://geosystems.ce.gatech.edu/Faculty/Mayne/papers/schneider_etal_1999.pdf
WebOscillatory or dynamic shear rheology is a sensitive method for detecting the formation of possible CNT networks and in qualifying the distribution of CNTs within a polymeric material without the need for laborious microscopy and imaging techniques. By way of example, the rheological properties of virgin PET and composites of PET with 0.5 wt%, 3 wt% and 7 … WebMar 23, 2024 · The dynamic shear modulus, or modulus of rigidity, is found using the fundamental torsional resonant frequency. Dynamic Young's modulus and dynamic shear modulus are used to compute Poisson's ratio. 1.2 This test method is specifically appropriate for materials that are elastic, homogeneous, and isotropic ( 1 ). 2
