Abstract EN
During rock breaking by drill, cone rolls on the rock surface and contact between gear teeth and surface is basically positive Mode-I plane indentation and bias Mode-I plane indentation.
During bias action, there will be an asymmetrical Mode-I singular stress field at both ends of the indenter.
The stress field singularity is of the same order as Mode-I crack tip and with the same function distribution.
In this paper, based on the J2 integral conservation law, a new method is established for solving stress intensity factor of bias Mode-I plane indentation, which not only provides respective stress intensity factor of both ends of the indenter but also compares relations between eccentricity, partial load, and stress intensity factor.
The study not only provides a method for establishment of new cone drill engineering design but also improves rock layer boring efficiency.
