Rock tests in nonuniform fields of tensile stresses
V. P. Efimov Institute of Mining, Siberian Branch, Russian Academy of Sciences, Novosibirsk, 630091, Russia
Abstract:
This paper presents experimental data on the strength of samples tested for bending and diametrically compressed core-shaped samples with a central hole. The obtained strengths of the samples are compared with the strength of samples under uniaxial tension using nonlocal strength criteria. It is shown that the calculated and measured strengths of the rock samples are in good agreement with each other when using a common approach to strength evaluation based on the Neuber–Novozhilov integral fracture criterion.
Keywords:
strength, tension, bending, Brazilian method, structural parameter.
