摘要：

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. © 1990.
