Dynamic shear modulus
WebAug 20, 2014 · Question #1: The geotechnical report does however give static soil properties. The area is primarily meta-sandstone. I'm looking for a formula that relates the dynamic shear modulus of rock (specifically sandstone) to the static shear modulus. Is there such a thing? Question #2: The static shear modulus is given in the report as 80 … WebThe DSR measures a specimen’s complex shear modulus (G*) and phase angle (δ). The complex shear modulus (G*) can be considered the sample’s total resistance to deformation when repeatedly sheared, while …
