Investigation of creep of some rocks
Authors:
Abstract
To fully characterize rocks, it is necessary to take into account their rheological properties, one manifestation of which is creep. Creep testing of rocks under uniaxial compression requires the use of rather heavy equipment-special spring presses. The strain is measured between the ends of the rock specimen, while a homogeneous stress state is observed only in the middle part along its height. In the study of rock creep by bending test of the specimen, simpler setups are used and at a certain ratio of the span of the specimen to its height, the stress state can be considered close to homogeneous.
