samples are water saturated, the bulk modulus of the rock is frequency dependent. Modeling with Gassmann’s equations predicts the measured saturated rock bulk modulus for all ﬂuids for frequencies below 20 Hz but underpredicts the water-saturated basalt bulk modulus for frequencies greater than 20 Hz. The most likely reason is that the pore ...

Values of tensile and cohesive strength for the basaltic rock mass are approximately one to two orders of magnitude lower than corresponding values for intact basalt. Temperatures comparable to those at the Venus surface may slightly increase the deformation modulus but decrease the compressive strength of the rock mass.
properties of volcanic rock remains largely unknown. Modelling of Mt. Etna has previously assumed values of Young’s modulus ranging from 50-100 GPa and a Poisson’s ratio of 0.25 [Cayol and Cornet, 1998; Bonaccorso and Davis, 1999]. • Here we report new results from stress-cycling deformation experiments on Etna basalt.

The bulk modulus (or ) of a substance is a measure of how resistant to compression that substance is.It is defined as the ratio of the infinitesimal pressure increase to the resulting relative decrease of the volume. Other moduli describe the material's response to other kinds of stress: the shear modulus describes the response to shear, and Young's modulus describes the response to linear stress.

deformation modulus of rock masses was made by Hoek and Diederichs (2006). This chapter presents the most recent version of the Hoek-Brown criterion in a form that has been found practical in the field and that appears to provide the most reliable set of results for use as input for methods of analysis in current use in rock engineering.

Feb 01, 2020 The dry rock bulk modulus is calculated using Lee's (2005) method that employs Pride's (2005) and MacBeth's (2004) equation to link the dry bulk modulus to the porosity and effective pressure. The estimated dry bulk modulus is then inserted to Gassmann's equation to estimate the saturated bulk modulus and velocity log (Fig. 4a). 2.4.2. Model 2
