Abstract The effects of partial closure and frictional slip of three-dimensional cracks on the stress intensity factors are studied using the eigenstrain method. The formulation, based on the correct modelling of the boundary conditions on the crack faces, is presented separately for partial closure and frictional slip, and applied to two simpler cases: partial closure of a surface-breaking crack normal to the free surface and under a residual stress field; and frictional slip of a completely closed crack under normal and shear tractions. The evolution of crack closure with the increase of crack depth and its influence on the stress intensity factor are examined and compared with a simple model for the first problem. the effect of coefficient of friction between crack faces on the stress intensity factors is investigated for the second problem.
