chanics.Rock indentation is an important and complicated problem among rock engineeringissues. In this paper, in addition to the fracture criterion of maximumtangential stress adjacent to crack tip, the higher order displacement disments i.e.quadratic elements, has been used to calculate displacement discontinuities andalso to reduce the singulari pared the theoretical andexperimental results cited in the literature which always show a percentageerror less than one percent. The simulated results may pave the way forincreasing the efficiency of mining and drilling by improving the design oftools and indentation equipments.
