Dynamic modulus (sometimes complex modulus ) is the ratio of stress to strain under vibratory conditions (calculated from data obtained from either free or forced vibration tests, in shear, compression, or elongation). It is a property of viscoelastic materials. 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. martin pecina dvtvWebJun 1, 2024 · Here, the normalized dynamic shear modulus G of the rubber-sand mixtures with varying RC is described by the Davidenkov model, which is simple and robust with only three model parameters [10]: (2) G G max = 1-γ / γ 0 2 B 1+ γ / γ 0 2 B A where A, B and γ 0 are model parameters. The γ 0 is the reference shear strain at G/G max = 0.5. martin parnell marathon
