Hai Friends,
I need to calculate the stress intensity factor at a crack tip using Displacement extrapolation method. After defining the local coordinate system at crack tip and activating it, I define the crack path and use KCALC command.
But an error pops up saying 'The crack face is not parallel to the currently active X-axis. The Kcalc command cannot be executed'
Please help me to resolve this problem, thank you
