  • This paper examines the elastic solution of stress and displacement around a circular opening on the condition that the lateral pressure coefficient equals 1 firstly. The paper further derives the analytic solution of elasto-plastic stress and displacement for the axisymmetric plane strain problem around a circular opening. In the derivation, the Hoek-Brown impirical criterion is used as the limiting equilibrium condition.
