Impact Analysis using HyperMesh & Radioss

Hello all,

I'm performing an impact analysis in HyperWorks using Radioss profile. My query is regarding the postprocessing the damage area in HyperView.

Impact analysis -> impact of a composite plate using spherical steel ball

While setting up the solver deck in HyperMesh (Profile: Radioss), I have used the following control cards to evaluate the damage areas:

/ANIM/BRICK/TENS/DAMA/

/ANIM/BRICK/DAMA/

While postprocessing, in HyperView, I can see only the damaged elements (deleted elements) on the composite plate. I can't see the display of damaged area in the legends. My query is, how to measure the damaged area on the composite plate. Is there any control cards I can use to measure the damaged area ? Can we see the damaged area in the legends ?

Thanking you,

--

Rajesh

    Hi Rajesh,

    /ANIM/BRICK/TENS/DAMA is only compatible with concrete material law (/MAT/LAW24). So it is expected you don't see anything with composite. 

     

    /ANIM/BRICK/DAMA should work if you have a failure criteria defined (like /FAIL/HASHIN for instance). 

     

    In order to answer to you as best as possible could you please answer to the following questions:

    • What is the material law you are using?
    • What is the damage model you are using?
    • What is the element type you are using?

    Thanks !

    Regards,
    Mathis.

    Few composite plates are made of only unidirectional or woven plies

    And, few are the combinations of both unidirectional and woven plies
