Unformatted text preview: is used to get fracture mechanics stress intensity factor (KI) by displacement extrapolation (KCALC command), and J-Integral methods. A user file JIN1 is created in the input. It consists of path operations necessary
to compute the J-Integral. In general usage, the user file would be available in the local directory rather than
being created in the input. Results Comparison
