The equipment used was a resonant-column apparatus manufactured by Wykeham Farrance and the tests were performed with relative density values of 20, 40, 60 and 80%, effective consolidation pressures of 50, 100, 150, 200, 250 and 300 kPa, and torsional excitations of 0.025, 0.05, 0.1, 0.2 and 0.4 volts (V), leading to shear strains (γ) between 0.002% and 0.023%. The results led to very simple empirical expressions for the shear modulus as a function of the angular strain for different effective consolidation pressures and void-ratio values.20172018-06-18 11:42:06Znanstveno delo70894ISSN: 1854-0171OceCobissID: 215987712COBISS_ID: 302998784ISSN pri članku: 1854-0171NUK URN: URN:SI:UM:DK:00FLOXQGslFakulteta za gradbeništvo, prometno inženirstvo in arhitekturo Univerze v Mariboru
