Abstract
The problem of hydraulic fracture development near a circular cavity is considered in a three-dimensional homogeneous elastic medium. The results of numerical calculations using the extended finite element method (XFEM) implemented in the ABAQUS software package are presented. Different variants of the position of an initial disk fracture relative to the cavity are considered. Some patterns of a 3D hydraulic fracture development near the cavity are found.
