... Abstract En-echelon fractures have been often identified in faults in rocks at different length scales. To enhance our understanding of the role of en-echelon cracks in the formation of a shear rupture, blocky Carrara Marble specimens, containing multiple artificial en-echelon flaws (about 13...

... Abstract Circular diamond sawing is a widely applied method in marble, granite and other natural stone block cutting operations. Cutting, squaring and some sizing operations of the plates are also carried out by circular diamond sawing machines. The different characteristic structures...

... in air. Macedonian marble was used as a rock sample. To measure subcritical crack growth, we used the load relaxation method of the double-torsion test. It was shown that the crack velocity increased when the temperature was higher at a constant relative humidity. In addition, crack velocity increased...

... the effects of water saturation on the strengths of marbles, the UCS, BTS and I s tests were carried out on eight different marble types in the laboratory. The evaluation of results showed that the strength losses due to saturation ranges from 5.0 % to 25.3 % for UCS, from 5.1 % to 20.9 % for BTS...

.... The application of modified criterion is then examined for two rock materials namely: Italian light marble and Saudi Arabian limestone. It is shown that the modified criterion which uses the effects of non singular stress term along the boundary of fracture process zone can provide much better predictions than...

... ABSTRACT In this research, mixed mode crack growth behaviour of Dehbid marble is assessed by means of the cracked beam specimen under asymmetric four-point bend (AFPB) loading. The specimen is a suitable configuration for testing rocks and geo-materials. The stress intensity factors are also...
