From these solutions analytic expressions of the plastic η p factors are derived. These results are then compared with those η p factors obtained using the EPRI's finite element analyses for power law strain hardening materials in order to assess the extent to which they can be approximately applied in J-integral tests with these specimens containing both deep and shallow cracks. It appears that in the deep crack specimens the η p factors are approximately equal for all hardening materials implying that the η p factors derived from slip line field solutions are accurate enough for J-integral evaluation. In the shallow crack specimens, with the exception of the double-edge cracked panels and pure bend specimens, the η p factors do not agree very well and reasons for the discrepancies are discussed.
