Abstract


The purpose of this study was to determine the SIF stress intensity factor by numerical modeling of a structure containing a hole playing the role of  a discontinuity " crack " subjected to a tensile load by the J- integral approach . The energy release rate was defined by modeling the crack by a notch and a double notch starting from the hole. The results were validated experimentally by testing a transparent material using the photoelasticity technology.
