Реферат:
An experimental study of the hydraulic fracture of thick-walled cylinders with the
application of a diametrical load was carried out on specimens in the form of cylinders with a
central circular hole and a circular hole located at a distance of half the radius from the center
of the cylinder at an angle of 45 degrees to the load application line. Specimens were made of
concrete based on aluminous cement. Ultimate stresses in the material were determined for two
types of stress state: under tension in bending conditions and under a compound stress state on
the surface of the hole. The modeling of the fracturing process taking into account the
inhomogeneity of the stress state near the hole was carried out using the boundary elements
method (in the variant of the fictitious load method) and the gradient fracture criterion.
Calculation results of the ultimate pressure were compared with experimental data.
Experimental study showed scale effect in concrete specimens with stress concentrators.
