A DIGITAL IMAGING ALGORITHM FOR EXTRACTING STRESS INTENSITY FACTOR FROM THE PHOTOELASTIC FRINGE PATTERN

[[abstract]]An algorithm was developed on a digital photoelastic system for extracting stress intensity factor from the experimentally obtained photoelastic fringe pattern. The case of a strip containing an eccentric crack was studied in detail. Excellent agreement between the present experimental and available analytical results demonstrates the applicability of the algorithm on investigating the fracture problems[[fileno]]2020228010007[[department]]動機
