Paleostress determination in a rock by a fractographic method

Research output: Contribution to journalArticlepeer-review

9 Scopus citations


A fractographic technique, hitherto used in ceramics for the evaluation of fracture stress, is adapted here to calculate fracture paleostresses in rocks. An example from a granite in East Sinai is analyzed. The results obtained for the ranges of local paleofracture stress, the severest flaw size and the initial stress intensity factor agree reasonably well with previous evaluations of fracture stresses in granite and with direct observations of the rock's grain size.
