Numerical stress intensity factor in polymer structures

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.
