... variable and the results obtained were compared against the experimental result. Finally, a three-dimensional numerical model was developed using the calibrated parameters. The failure behaviour of the interface in the double-sided shear test was simulated accurately, and evolution of the exponential...

... thermal expansion coefficient was mea- sured in our laboratory. Tests were realized on cubic blocs (10 × 10 × 10 cm) following the European stan- dard EN 14-581, and also on cylindrical samples. We obtained nearly the same value whatever the shape of the sample = 6 3). 10 6 K 1 3 EXPERIMENTAL RESULTS...

... (DIC) analysis and finite elements numerical simulations. The test methods chosen are two types of Brazilian disc tests with a central notch (CCBD and CCNBD), the SCB and ASCB tests. The experimental results show that the obtained values for the mode I fracture toughness KIC vary between 0.62 and 0.68...

... of the falling blocks is presented. Experimental results show that the coefficient values decrease with both the increase of the block mass and the impacting velocity. The various scaling methods in literature are evaluated. Additionally, a momentum based scaling approach was found to be consistent...

... of joint rock, proposed seven-component non-linear shear creep model of rock is carried out the identification. The compar- ison between the shear creep model and experimental result shows that proposed non-linear shear creep model IS right and reasonable. INTRODUCTION Joint rock is a kind of complex...

... Concrete plug replacement is a treatment method for faults in concrete gravity dam foundations. To investigate the effects of concrete plug installation on the shear strength of dam foundations, direct shear tests are carried out for rock models made of plaster. From the experimental results...

... strength values obtained during laboratory tests, and the morphological parameters that were calculated from three-dimensional surface measurements. The experimental results confirmed that the shear strength of rock joints is direction-dependent, and show that the new surface parameters to can be used...

EXPERIMENTAL RESULTS AND PHYSICAL MODEL 3.1 Experimental results As was established during a series of experiments, a burst-like AE activity was observed immediately after unloading of pre-loaded granite...

... ABSTRACT: For the description of the compaction behavior of crushed rock salt for use as a backfill material in underground radioactive waste repositories, a constitutive model is proposed based upon phenomenological and theoretical considerations and experimental results. It can be shown...
