Reply To: XFEM Crack growth of internal crack in a 2D plate

Hi,

I received support from my ANSYS license provider and found the solution to my problem. I am sharing it with the community.

It was a problem within my code itself. I made mistake in specifying the normal to the crack front/tip plane. The direction of the crack propagation will be in X direction and for two crack fronts/tips, the direction of normals should be opposite to each other. The modified section of the code is as follows.

! New Local coordinate system for CINT definition at left side crack tip

WPSTYLE, , , , , , , , 1

WPROTA, 180

CSWPLA, 11, 0,

CSYS,0

 

! New Local coordinate system for CINT definition at right side crack tip

WPSTYLE, , , , , , , , 1

CSWPLA, 12, 0,

 

!Fracture Parameter calculations

CINT, NEW, 1 ! Crack ID for first crack front

CINT, NORM, 12, 2 ! Define the crack plane normal

 

CINT, NEW, 2 ! Crack ID for second crack front

CINT, NORM, 11, 2 ! Define the crack plane normal

 

Thanks.

Best regards,

Jose Mishael
