Hi everybody,

I found in RADIOSS help the /INICRACK card, but I'm not able to create it on Hypermesh. Where can I find it?

 

Regards,

    Hi Luke31,

    /INICRACK is an unsupported card in HyperMesh now, but will be updated in HyperMesh. This card can be added through HyperCrash. Please see the attached image.

    Meanwhile you can model crack initialization and propagation using XFEM card in HyperMesh. Various failure cards are available  /FAIL/XFEM_FLD, /FAIL/XFEM_JOHNS and /FAIL/XFEM_TBUTC.

    We have an example file Example 26 - Ruptured Plate in the Help Menu where failure of a circular plate subjected to the impact of an infinite rigid sphere is studied and failure model used is the Forming Limit Diagram (FLD).

    Thank you very much for your reply! Is it possible to use those model with solid elements or can I use them only on shell elements?

    Hi Luke31,

    These failure models are available for Shell elements only.
