A numerical method for the determination of stress intensity factors and stress concentration factors for cracks and notches has been presented by Nisitani. The method, known as the body force method, approximates a plate with a hole (or crack) by a plate without a hole but having body forces distributed along the boundary of the hole. This method has been implemented on the NRC-IBM 360 system and has been described in a previous report. This report describes and lists the computer programs that were used to determine the stress intensity factors or stress concentration factors for the five types of notch and crack problem described in that report.
