Rock mechanics

Development methods and testing equipments for investigations of conformities to natural law of deformation and destruction of rocks under multi-axial stress state conditions, laboratory has automation multi-axial loading testing system, which is used for laboratory testing of rock samples under multi -axial stress state conditions, geometry of sample in controlled under loading. Samples for testing are made in form of cubes with an edge from 30 mm until 100 mm/ Maximal pressure on the sample can reach to 500 MPa.

The experimental investigations on stationary and unstationary gas and fluid filtration is porous rock, which per mobility are sensitive to stress.

The experimental investigations of influence of the porous space structure of rock on their ultrasonic wave velocity.

The investigations on influents of stress state type and trajectory of loading on destruction work of rock.

The experimental check mechanical and mathematical modeling for oil and gas collectors deformation under decreasing rock seam pressure, including from its anomaly high values. Mechanics of non-elastic deformation of constructive materials. The experimental research of processes of deformation and fracture for construction materials under simple and complex loading: research of temporal effects; research of influence anisotropy; variable - repeated loading; cyclic loading; loading on complex space trajectories; modeling of prestart of magisterial tubes.

The experimental investigations are making at the Instron multi - axial testing system ( tension 1000 kN, torsion 6500Hm, internal pressure 1500 bar) with control computer system.

There were designed the methods and additional equipment for investigations of deforming laws of ceramics in wide temperature range.
