  • J - Integral

    Hi there,

    I am trying to calculate the J integral around a crack between two concentric orthotropic cylinders, used to model a FRP component.

    The FE code is ANSYS.

    The crack tip node is 56, but at the end of the analysis in the status window the crack front node is shown as 55415 (which does not exist).
    Furthermore the J integral values are shown as zero for all contours.

    Not to mention the fact I am unable to get the command

    GET, J, CINT, 1,,56,,3

    to work, as I always get an error message on a mismatch with node 56 (in the command you are supposed to indicate the crack tip node).

    Hoping the problem is trivial I attach an input file.

    Also does anybody have good refernces on the use of the J - Integral for fracture mechanics problems in elastomeric / FRP composites?

    Thank you very much

    Best Regards

    Hi All,

    I have realized that wrong material properties are given in my input file, please find a correct version in case anybody wanted to try it.

    Thank you

    Kindest Regards
